It builds upon the success of the PSA-T series in offering a lightweight and truly handheld instrument that incorporates an extensive feature set. An improved user interface is combined with many new hardware and software features and a ruggedized casing. Genuinely hand-held The PSA Series II is sufficiently small and lightweight to fit comfortably into the hand - unlike most other so-called handheld spectrum analyzers. A removable screen protector and sun-shield combines with rubberised buffers top and bottom to enhance its use in the field. High resolution colour display The 4.3" TFT display provides a wealth of detailed information. Colour is used to clearly distinguish between multiple traces, markers and limit lines. PSA1302 - 1.3GHz PSA2702 - 2.7GHz A big feature set in a small instrument The PSA Series II incorporates the features most needed in a portable spectrum analyzer. 1MHz to 1300MHz or 2700MHz frequency range Resolution bandwidths of 1MHz, 280kHz or 15kHz -96dBm typical noise floor at -20dBm reference level Measurement in dBm or dBV, mV or W Zero span mode with AM and FM audio demodulation Trace modes of normal, peak hold and trace average Live, View and Reference traces in contrasting colours Twin markers with readout of absolute & difference values Smart marker movement with selectable peak tracking Frequency presets and independent state storage Auto-find automatically sets sweep parameters for The touch-screen uses a three row hierarchical menu system to provide fast and intuitive control of the many functions. Battery operation of more than 8 hours The PSA Series II operates from a Li-ion rechargeable battery that can provide more than eight hours of continuous operation. If switched off to conserve power, it returns to normal operation within two seconds of switch-on with all data retained. It can also be set to switch off automatically after a set time from the last action. For continuous bench top operation it can be powered from its AC adaptor which also recharges the batteries in less than 3 hours. Unlimited data storage With nearly 2GB of internal memory, the PSA Series II can store thousands of waveforms, instrument set-ups, or complete screen images. With option U01 installed, it can also log tens of thousands of results and make use of compensation tables and limit patterns. All files can be saved with either default file names or with user defined names using the alpha-numeric keypad. USB Flash drives can be used to copy and backup data, or transfer it to a PC for analysis. Alternatively a USB device interface is included for direct connection to a PC for file transfer. the highest signal found Unlimited storage for waveforms, set-ups and screens User assignable file names, file stamping from real-time clock USB interfaces for Flash drives and PC connection Comprehensive status and context sensitive help screens More than 8 hours continuous operation from a charge Smaller and lighter than other spectrum analyzers (weight only 0.56 kg) Option U01 adds: Limit lines and limit patterns with limits comparator Data logging of peak values, complete traces or screen images from timer, external trigger or limits comparator Sweep triggering from external trigger or limits comparator Compensation tables, fixed offsets and 75W compensation Capability to show screen contents on a PC The size a hand-held instrument should be ! Actual size Ruggedised casing See more detail The casing of the PSA Series II includes rubberised buffers top and bottom to help resist knocks and scratches. The large TFT display of the PSA Series II shows a wealth of information. It makes use of colour to clearly distinguish the traces (live, view and reference) from the markers, limit lines and graticule. The tilt stand can be moved to the top of the instrument to act as a screen protector when in transit. In this mode it can also act as a sun-shield when in the field. Detailed set-up information is shown above the graticule with marker readout and further status below. Comfortable to hold With a width of only 92mm (3.6") and a weight of only 560 grams (20 oz) the PSA fits comfortably into the hand. Context-sensitive help Touch-screen or hard-key control This can be automatically selected to relate to the current menu hierarchy. The PSA Series II incorporates extensive on-screen help information. The instrument is normally operated using its touch screen. Full status display The three-row hierarchical menu system provides rapid intuitive access to all functions . Instant access is provided to a multi-page status screen that shows the complete status of the instrument including detailed system information. Additional hard keys are provided for marker movement and for shortcuts to major functions. Alternatively, all of the functions can be operated with just the hard keys by using the five way navigator in a tab-enter-jog mode. Connectivity In addition to the RF input, the analyzer includes connectors for DC power, USB host, USB device, trigger in/out, and audio out. Instant On Built-in loudspeaker On pressing the power button, the instrument comes to life almost instantly, with the first sweep available in under 2 seconds. Audio de-modulation can be accessed via the built-in speaker or external phones. Transfer files to PC Also at home on the bench The PSA Series II will find plenty of applications on the bench as well as in the field. It's low cost enables every engineer to have access to a spectrum analyzer whenever they need one. For continuous bench-top operation, the supplied AC line adaptor powers the instrument as well as charging it. The PSA Series II can be used vertically, as well as horizontally or on its tilt stand. A USB device connector is provided which enables direct connection to a PC for bi-directional file transfer. A USB host connector enables USB Flash drives to be connected for additional storage or for cable-less file transfers. Live, View and Reference traces A view trace and reference trace can be displayed in addition to the live trace using contrasting colours for clarity. Intuitive menu system Extensive data storage Ease of use was a major consideration in the design of the PSA Series II. The PSA Series II can store almost unlimited amounts of data using its 1.8GB of internal memory supplemented, if necessary, by USB Flash drives. The filing system can store trace and state files, screen images, set-up files, logging files*, limit patterns* and compensation tables*. The menu system provides rapid access to five menu groups, each of which has up to five sub menus, each with their own function keys. Files are stored under either default file names, or user-chosen file names entered from an alpha-numeric keypad. The illustration is a truncated version of the real screen image which can list 20 files simultaneously. Each directory can contain up to 999 files. Function keys perform direct actions or create pop-up menus or dialogue boxes. Any number of traces can be saved to memory and rapidly recalled to the screen. Trace states are saved in addition to the traces and can be recalled separately. Smart marker movement Dual markers provide an on-screen readout of frequency and level including difference values. Frequencies can be set by direct numeric entry, or by a digit increment system. Centre, Start and Stop can be stepped by any chosen increment. Span can be zoomed in a 1-2-5 sequence. Single key shortcuts include Set to Peak, Set to Marker and Set between Markers. Frequency presets enable fast changes between frequently used sweep ranges. Trace write modes In addition to the normal mode, the trace can be set to display Peak-hold, or a Multi-sweep Average. Triggered sweep* The standard sweep modes of continuous repeat and single shot can be extended to include triggered sweeps from an external signal or internal limits comparison*. The markers can be set to specified frequency values, scrolled across the screen, or set to automatically find peaks. A peak tracking mode is also provided which will track the highest peak in the sweep despite changing frequency. Limit patterns and limits comparator* Limit lines and patterns can be defined which can be simply visual aids or create automatic actions. Zone restriction can be applied. Marker amplitude readout can be in graticule units (dBm or dBV) or in linear units (mV or W). Vertical expansion The vertical resolution of 10dB per division can be expanded to 5dB, 2dB or 1dB with panning over the full dynamic range. A single or dual line limits comparator can be used to generate audible warnings, output signals, or to freeze or log the trace. Zero span demodulation The PSA Series II includes a zero span mode with both AM or FM audio demodulation. The audio signal, with variable volume and selectable low-pass filter, is available from the built-in loudspeaker or from a standard 3.5mm jack socket. *Optional Features Features marked * are available with option U01 installed. Files are time-stamped from the real-time clock, and can be listed by date or name. Full Status display In addition to the extensive on-screen status information, a single button press reveals the complete set-up of the instrument as a screen listing. All settings are retained when at power-down, and any number of set-up files can be stored under automatic or user names. Data export and transfer USB device and host connectors are provided enabling the PSA Series II to be linked directly to a PC for file transfer, and for the connection of USB Flash drives for data transfer or storage. Trace files have a standard comma separated value (.csv) format which can be imported into other applications such as Excel or MathCad. Screen images are stored as standard bit-maps that can be manipulated and printed using a PC as well as being recalled to the PSA screen. Offsets and Compensation Tables* The reference level, graticule and marker readouts can be set to compensate for external attenuation or gain to a resolution of 0.1dB. Compensation can also be added for signals emanating from a 75W source. Tables can be loaded that compensate for variations of level with frequency for specific antennae or transducers. The tables can contain up to 100 points and are linearly interpolated between points. Data Logging* The PSA Series II can log results in response to a variety of stimuli. Data is stored as files that can be transferred to a PC for analysis using PSA-Manager software. The data stored can be the peak level, centre frequency level, the whole trace, or a bitmap screen image. Each file can contain up to 9,999 entries. The 1.8GB of internal memory enables vast amounts of data to be stored. Logging entries can be created by an internal timer (adjustable from seconds up to hours), the manual trigger key, the external trigger input, or the limits comparator. PSA-Manager Software PSA Manager is a Windows* based program that provides additional capabilities for the PSA Series II. It can display trace files, and can back up and manage set-up files and other parameters into project folders. However, its more sophisticated capabilities are apparent when option U01 is installed within the instrument. It can be used to create limit pattern and compensation table files, using numeric editing, import from .csv files, or its graphical editor. Log files created within the instrument can be viewed and analyzed. View on PC* View on PC enables the screen of the spectrum analyzer to be sent to a PC by USB. The screen image can be set to a user definable size and is particularly useful for education and training purposes.
