AP AMP MSL [Application (Optical AMP Memory Select)]
■ Function
Selects a measurement memory for optical AMP measurement.
Setting/read is enabled only in the optical AMP measurement mode.
Header Program Query Response
AP AP AMP, MSL,s AP ? AMP,MSL AMP,MSL,s
■ Value of s
s indicates a measurement memory.
s = PIN: Pin memory used to measure the light input to the optical amplifier.
= POUT: Pout memory used to measure the light output from the optical am-
plifier.
■ Initial setting value
s = PIN
AP AMP CAL [Application (Optical AMP Resolution Calibration)]
■ Function
Calibrates the resolution of the spectrum analyzer for optical AMP measurement.
When the calibration is complete, bit 4 (execution complete bit) of the extended
event status register (ESR2) is set to 1.
Setting/read is enabled only in the optical AMP measurement mode.
Header Program Query Response
AP AP AMP,CAL,n AP ? AMP,CAL AMP,CAL,m
■ Value of n
Program
Make the following setting with n.
n = 0: Specify the current resolution calibration data as the default.
= 1: Carry out resolution calibration to obtain resolution calibration data.
Response
m indicates a resolution calibration state.
m = 0: Resolution calibration has been terminated normally.
= 1: Resolution calibration has been interrupted due to an insufficient
light level.
= 2: Resolution calibration has been interrupted due to any other fault.
