SR200 Gate Scanner
The SR200 Gate Scanner module is designed to automate
waveform recovery with the SR250 and SR255 gated
integrator modules. Waveform recovery is done by slowly
scanning the gate of the integrator over the waveform of
interest. Both the SR250 and SR255 modules have external
gate delay control inputs. The SR200 provides an adjustable
ramp voltage needed to scan the gates using these inputs.
The initial and final delays, as well as the scan time, are
fully adjustable. Single or repeated scans may be performed
in the forward or reverse direction over any portion of the
waveform. Scan times from 10 milliseconds to 5 minutes may
be selected.
In addition to the delay control output, the SR200 has a 0 to 10
V X-axis ramp output designed to drive the X-axis of a chart
recorder or an oscilloscope.
