Gated
Waveform runs while the gate signal is true and stops while false.
Carrier waveforms: All standard and arbitrary.
Maximum carrier
frequency:
The smaller of 1 MHz or the maximum for the selected
waveform.
40 M samples/s for arb and Sequence.
Trigger repetition rate: 0.005 Hz to 100 kHz internal
DC to 1 MHz external.
Gate signal source: Internal from keyboard, previous channel, next channel or
trigger generator.
External from
TRIG IN or remote interface.
Gate start/stop phase: ± 360 ° settable with 0.1 ° resolution, subject to waveform
frequency and type.
Sweep
Frequency sweep capability is provided for both standard and arbitrary waveforms.
Arbitrary waveforms are expanded or condensed to exactly 4096 points and DDS
techniques are used to perform the sweep.
Carrier waveforms: All standard and arbitrary except pulse, pulse train and
sequence.
Sweep mode: Linear or logarithmic, triggered or continuous.
Sweep direction: Up, down, up/down or down/up.
Sweep range: From 1 mHz to 16 MHz in one range.
Phase continuous.
Independent setting of start and stop frequency.
Sweep time: 30 ms to 999 s (3 digit resolution).
Marker: Variable during sweep.
Sweep trigger source: The sweep may be free run, triggered manually from the
keyboard, or triggered externally from the
TRIG IN input or
the remote interface.
Sweep hold:
Sweep can be held and restarted by the HOLD key.
Multi channel sweep: Any number of channels may be swept simultaneously but
the sweep parameters will be the same for all channels.
Amplitude, offset and waveform can be set independently
for each channel.
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.
Carrier waveforms: All waveforms except pulse, pulse train and sequence.
Frequency list: Up to 16 frequencies from 1 mHz to 10 MHz.
Trigger repetition rate: 0.005 Hz to 100 kHz internal
DC to 1 MHz external.
Usable repetition rate and waveform frequency depend on
the tone switching mode.
Source: Internal from keyboard, previous channel, next channel or
trigger generator.
External from
TRIG IN or remote interface.
