Channel Current
Gain Calibration
Registers
The Channel Current Gain Calibration Registers store current gain
calibration constants in non-volatile memory. There are 16 registers,
one for each output channel. The register at base + 160
16
stores channel 1,
base + 162
16
stores channel 2, up to base 17E
16
to store channel 16. This
register is non-volatile.

WRITE Unused Current Gain Calibration Constant
Current Gain Calibration Constant: Writing a 16-bit value to this field
sets a new constant used to calibrate the channel output. Values are in the
range:
000
16
minimum gain
800
16
nominal gain
FFF
16
maximum gain
Notes Registers 00100

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.
