Refer to the RP793xA, RP794xA and RP795xA, RP796xA characteristics tables for the model-specific
resistance programming ranges.
Front Panel Menu Reference SCPI Command
Select Output\Advanced\Resistance.
Specify an Output Resistance value. Then check the
Enable box. Then press Select.
To select a resistance of 0.5 ohms:
VOLT:RES 0.5
To enable output resistance:
VOLT:RES:STAT ON
When units are paralleledd, the programmable output resistance is reduced. The
programmable output resistance for a single unit must be divided by the total
number of paralleled units.

This information applies to models RP795xA and RP796xA only.
Voltage compensation modes let you optimize output response time with capacitive loads.
High1 compensation setting provides maximum up-programming speed as well as the fastest
transient response settling time. This mode is optimized for use with resistive loads; however
capacitive loads up to the limits outlined in the table below can be used when using load leads shorter
than 3 meters (10 feet). Exceeding these limits can lead to voltage programming overshoots and
transient response instability.
Low compensation setting is optimized for use with large capacitive loads up to the limits shown in the
table below, along with load leads longer than 3 meters (10 feet). In this mode, the up- and down-
programming speed and voltage control-loop bandwidth are limited to prevent voltage programming
overshoots and improve transient response stability. Low mode provides the best stability and
overshoot minimization over all load configurations.
<frequency> specifies the low-pass corner frequency of a filter applied to the programming signal.
Refer to the frequency description in the next section
Connecting very low ESR capacitors larger than the High mode limit with load leads
shorter than 3 m (10 ft.) is not recommended in either bandwidth range. This load
configuration can lead to voltage programming overshoots.
