SR785 Dynamic Signal Analyzer
Capture Menu
The Capture menu configures the Capture Buffer. See ‘Capture Buffer’ in Chapter 2 for
more information.
Capture Channels
Select which inputs to capture [Ch1, Ch2, Ch1+Ch2]. Choose either input or both inputs.
Capturing a single input limits playback to measurements of a single input.
Capturing both inputs allows playback of all measurements but the Capture Length will
be half as long as for a single input.
When the measurement group is order. Capture Channels is always set to Ch1+Ch2.
Turn off Auto Offset during capture to avoid interrupting the input signal.
Command: CCHN (?) {i}
Capture Mode
Select the Capture Mode [1 Shot, Continuous].
Press [Start Capture] to begin storing data in the capture buffer. If the Capture Mode is 1
Shot, capture stops when the buffer is full. Press [Stop Capture] to halt capture before
the buffer is full.
If the Capture Mode is Continuous, once capture is started, it continues indefinitely and
fills the capture buffer in a circular fashion. In this case, press [Stop Capture] to halt
capture with the most recent data in the buffer.
Continuous capture is not allowed in the order measurement group.
