OPERATING MODES
Continuous
Continuous cycles of the selected waveform are output at the programmed frequency.
Sweep
Carrier Waveforms: All
Sweep Mode: Manual, linear or logarithmic, single or continuous.
Sweep Width: From 0.1Hz to 10MHz in one range. Phase continuous. Independent setting
of the start and stop frequency.
Sweep Time: 100ms to 999s (10ms resolution).
Sweep SYNC: Start of sweep trigger available from SYNC output.
Trigger Source: The sweep may be free run or triggered from the front panel MAN TRIG key.
Manual Sweep Mode: An analogue control can be used to set any frequency between the sweep
start and sweep stop frequencies.
Amplitude Modulation
Carrier Frequency: From 1mHz to 10MHz.
Carrier Waveforms: All
Modulation Frequency: 400Hz internal. DC to 20kHz external
External Modulation: AM/COUNT IN socket
Frequency Shift Keying (FSK)
Phase coherent switching between two selected frequencies at a rate defined by the switching signal
source.
Carrier frequency: From 0.1Hz to 10MHz.
Carrier waveforms: All
Switch repetition rate: DC to 10kHz (internal trigger).
Switching signal source: Manual (front panel MAN TRIG key) or internal trigger generator
Frequency List
Carrier Waveforms: All
Frequency List: Up to 10 frequencies from 1mHz to 10MHz
Switching Source: Manual from front panel MAN TRIG key
OUTPUTS
Main Outputs
Output Impedance: 50W and 600W (not independent)
Amplitude: 2mV to 20V pk-pk open circuit, (1mV to 10V pk-pk into 50W/600W) in four
switch selectable ranges with 20dB vernier control within each range.
(Amplitude can be displayed in pk-pk or r.m.s.)
Attenuator: 0, -20dB, -40dB, or -60dB.
Amplitude Flatness: ±0.2dB to 500kHz; ±2dB to 10MHz.
DC Offset Range: ±10V. DC offset plus signal peak limited to ±10V from 50W/600W;
CLIP shows in display when offset plus signal peak exceeds ±10V. DC offset
plus waveform attenuated proportionally by the attenuator.
Resolution: 3 digits for both Amplitude and DC Offset.
OUTPUTS (Continued)
SYNC Out
Automatically selected to be either Waveform Sync or Sweep Sync:
Waveform Sync: A square wave at the main waveform frequency. Symmetry is 50% for sine
and triangle waves at MAIN OUT; for square waves symmetry is the same as
that of the waveform at MAIN OUT.
Sweep Sync: Outputs a trigger signal at the start of sweep to synchronize an oscilloscope.
Output Signal Level: Output impedance 50W nominal. Logic levels of <0.8V & >3V.
INPUTS
AM In
The AM/COUNT IN socket is set to AM input when External AM is selected
Input Impedance: 40kW
Input Sensitivity: Approximately 2V peak-peak for 100% modulation.
Max. Allowable Input: ±10V
Count In
The AM/COUNT IN socket is set to external frequency measurement when EXT COUNT is selected
Input Impedance: 1MW/20pF
Input Sensitivity: 50mVrms (sinewave)
Max. Allowable Input: 30Vdc/30Vrms to 50Hz/60Hz with respect to ground, reducing to 1Vrms
above 1MHz.
DISPLAY FUNCTIONS
The LCD shows generator frequency at a resolution of 4 digits simultaneously with output amplitude/
offset, together with various status annunciators.
Alternatively, the generator frequency can be displayed without the amplitude/offset to a resolution
of 6 digits. The LCD also functions as the external frequency measurement display with up to 7 digits
of resolution.
Internal Measurement Accuracy
Amplitude: Display shows peak-to-peak amplitude or rms value. Display corrected for
attenuator setting. 3-digit resolution, accuracy typically ±5% of full scale.
DC Offset: 3-digit resolution; accuracy typically ±2% setting ±1 digit. Display corrected
for attenuator setting.
Frequency Setting: Resolution up to 6 digits, see Waveforms section for setting accuracy.
EXTERNAL FREQUENCY MEASUREMENT
Frequency Range: 3Hz to >120MHz.
Resolution: Up to 7 digits
Input Sensitivity: better than 50mVrms (sinewave).
Measurement Time: Automatic.
Accuracy: ±1 digit ± timebase accuracy.
Timebase Accuracy: ±5ppm initial error; ± 5 ppm/year ageing rate; typically < 0.1ppm\°C.
