Note A different gain value is required for voltage and current output operation.
Undefined Registers
The registers from C0

through FE
16
are undefined.
Channel Voltage
Offset Calibration
Registers
The Channel Voltage Offset Calibration Registers store voltage offset
calibration constants in non-volatile memory. There are 16 registers, one
for each output channel. The register at base + 100
16
stores channel 1,
base + 102
16
stores channel 2, up to base 11E
16
which stores channel 16.
This register is non-volatile.

WRITE Unused Voltage Offset Calibration Constant
Voltage Offset Calibration Constant: Writing a 12-bit value to this field
stores a new constant used to calibrate the channel output. Values are in the
range:
000
16
maximum positive offset
800
16
nominal (zero) offset
FFF
16
maximum negative offset
Notes Registers 00100
16
through 001BE
16
are located in non-volatile (FLASH)
memory. Writing to this memory requires a complicated sequence of
register accesses not documented here. It is recommended that calibration
be performed using the SCPI driver for the module, not register access.
Non-volatile memory has finite life, based upon the number of writes. Use
care when writing to this memory.
The contents of this register are loaded into volatile memory at power-on
and not used on an on-going basis.
