Set the Output Bandwidth - RP793xA, RP794xA

This information applies to models RP793xA and RP794xA only.
Voltage compensation modes let you optimize output response time with capacitive loads.
The Capacitive Load Boundary
function of DUT capacitance to allow for stable operation.
Comp 0 (High speed/Small capacitive load) – provides the fastest programming speed and transient
response time. Best suited for resistive DUTs with low capacitance. Default frequency = 1.4 kHz.
Comp 1 (Medium speed/Medium capacitive load) – provides intermediate programming speed and
transient response time. Best suited for DUTs with higher capacitance with some trade-off in
programming speed and transient response. Default frequency = 460 Hz.
Comp 2 (Slow speed/Large capacitive load) – best suited for DUTs with high capacitance/low ESR
with the trade-off of a slower programming speed and transient response. Default frequency = 55 Hz .
<frequency> specifies the low-pass corner frequency of a filter applied to the programming signal. The
programmed voltage is a digitized signal which passes through a single-pole low pass filter where the
pole is specified in Hertz. This filter has the effect of slowing down the output with respect to changes
in the programmed voltage or current. This, in combination with the configurable slew setting, allows
for a trade-off between programming speed and output voltage or current overshoot. For example,
increasing the filter frequency may result in more overshoot and decreasing the frequency will lower
the overshoot, depending on the compensation setting and the load impedance. This frequency
setting does not affect the unit's transient response to a load change.
The following table summarizes the effect that the compensation settings have on the CV
Programming Speed Characteristics.
Setting
Comp 0 no load, 10-100% of rating
full CC load, 0-100% of rating
Comp 1 full CC load, 0-100% of rating
Comp 2 full CC load, 0-100% of rating
