Tone Switching
Capability provided for both standard and arbitrary waveforms. Arbitrary waveforms are expanded
or condensed to exactly 4096 points and DDS techniques are used to allow instantaneous
frequency switching.

Using 2 channels with their outputs summed together it is possible to generate DTMF test signals.
Trigger Generator
Internal source 0.005 Hz to 100kHz square wave adjustable in 10us steps. 3 digit resolution.
Available for external use from any SYNC OUT socket.
OUTPUTS
Main Output - One for each channel

All waveforms except pulse, pulse train and sequence.
Up to 16 frequencies from 1mHz to 40MHz.
0.005Hz to 100kHz internal
dc to 1MHz external.
Usable repetition rate and waveform frequency depend on the
tone switching mode.
Internal from keyboard, previous channel, next channel or trigger
generator.
External from TRIG IN or remote interface.
The tone is output while the trigger signal is true and stopped, at
the end of the current waveform cycle, while the trigger signal is
false. The next tone is output when the trigger signal is true
again.
The tone is output when the trigger signal goes true and the next
tone is output, at the end of the current waveform cycle, when
the trigger signal goes true again.
The tone is output when the trigger signal goes true and the next
tone is output, immediately, when the trigger signal goes true
again.
50Ω
5mV to 20Vp−p open circuit (2.5mV to 10Vp−p into 50Ω).
Amplitude can be specified open circuit (hi Z) or into an assumed
load of 50Ω or 600Ω in Vpk−pk, Vrms or dBm.
2% ±1mV at 1kHz into 50Ω.
±0.2dB to 1MHz; ±0.4dB to 40MHz
±10V. DC offset plus signal peak limited to ±10V from 50Ω.
Typically 3% ±10mV, unattenuated.
3 digits or 1mV for both Amplitude and DC Offset.
