Dual-channel WaveGen — built-in function/arbitrary waveform generator (Specification are typical) (Option)
WaveGen outputs/
Output modes
Two (front-panel BNC connectors)
Both waveform generator outputs can be frequency tracked, amplitude tracked, or completely tracked. Phase adjustable.
1
A generator’s output can be inverted to create a differential signal
Output modes: Normal (continuous) or single-shot (limited to arbitrary, sine, ramp, sine cardinal, exp rise/fall, cardiac,
Gaussian pulse)
Waveforms Sine, square, ramp, pulse, DC, noise, sine cardinal (sinc), exponential rise, exponential fall, cardiac, Gaussian pulse, and
arbitrary
Modulation Modulation is available on channel 1 only. Modulation is not available when tracking mode is enabled
Modulation types: AM, FM, FSK
Carrier waveforms: sine, ramp, sine cardinal, exponential rise, exponential fall, and Cardiac.C176
Modulation source: Internal (no external modulation capability)
AM:
Modulation: Sine, square, ramp
Modulation frequency: 1 Hz to 20 kHz
Depth: 0 to 100%
FM:
