Explanation
This command sets the optical frequency (wavelength) to the value specified in
<wavelength>. The actual optical frequency (wavelength) setting range and reso-
lution depend on the unit specification. The response messages are outputted in
frequency unit at the order of the channel list.
MFRame:FETCh:POWer
Function
Inquiries the measured data.

Explanation
This command returns the currently measured data. It is valid only for the optical
sensor unit. The measured data are output in dBm depending on the order of the
channel list. (Cannot read the data in W.)
Each optical sensor unit does not measure the data synchronizing with other units.
The data of each unit is the latest one at the time of inquiry, that is, they are not the
data acquired at the same time.
