CALibrate:ARM[:VALue] <arm input voltage>
The CALibrate:ARM:VALue command performs a gain and zero calibration on
the ARM input. This command requires an <arm_input_voltage> calibration
source set to 0.0 ±0.001 V for calibrating the offset, and 20.0 V ±0.1% for
calibrating the gain.
CALibrate[<channel>]:DELay <cross channel specification>
Performs calibration of the internal delay cabling for the channel specified. This
command requires an input frequency source set to a 10 MHz square wave at
±1.0 V ±0.1 V.
This command performs cross-channel delay calculations between the two input
channels. It requires the 10 MHz square wave to be connected to both channel
inputs of the instrument using a “T” connector and cables of equal length.
The <channel> argument specifies which of the two standard Counter channels
you want to calibrate.
CALibrate[<channel>]:HYSTeresis
The CALibrate[<channel>]:HYSTeresis command calculates the hysteresis
linearization factors. This command uses an internal reference, and so does not
require any external input.
The <channel> argument specifies the channel being calibrated, and can be
specified as either 1 or 2. If <channel> is not specified, channel one is assumed.
CALibrate[<channel>]:LFCOmp
The CALibrate:LFCOmp command performs a low frequency compensation on
the inputs. This command requires an input frequency source set to a square
wave of ±2.5 V ±0.1 V at 1 kHz.
The <channel> argument specifies the channel being calibrated, and can be
specified as either 1 or 2. If [<channel>] is not specified, channel one is
assumed.
CALibrate[<channel>]:LINearity
The CALibrate[<channel>]:LINearity command calculates linearity corrections
for the preamplifier section of the Counter hardware. This command requires an
input calibration source set to 0.5 V ±0.1%.
The <channel> argument specifies the channel being calibrated, and can be
specified as either 1 or 2. If [<channel>] is not specified, channel one is
assumed.
CALibrate[<channel>]:VALue <input voltage>
The CALibrate[<channel>]:VALue <input voltage> command calculates the gain
