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
