4-74 Chirp Source Menu
SR785 Dynamic Signal Analyzer
With External Trigger, the chirp waveform is triggered along with the FFT time record.
Set the Trigd Source Mode to Continuous to trigger the source with every time record.
Do not use Ch1 or Ch2 input trigger since the output will not start until a trigger is
received.
Command: CBUR (?) {x}
Source Display
Select the Source Display [DisplayA, DisplayB]. The Source Display only applies for the
FFT Measurement Group.
The Source Display is the display which determines the burst period (FFT time record)
and the bandwidth for bandlimited noise and chirp (FFT Span). There is a single Source
Display for both Chirp and Noise outputs. Changing this entry for one type of source
also changes it for the other.
Select which display sets the time record and frequency span of the chirp. If the other
display has a different span, the chirp will not be appropriate for that span.
Burst Chirp is a percentage of the Source Display FFT time record length.
Command: CSRC (?) {i}
