Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition 27
Channel numbers apply to modules that have two inputs/outputs, for
example, the Agilent 81635A Dual Power Sensor.
Modules with two channels, for example, the Agil ent 81635A Dual Power
Sensor, use the channel number to distinguish between these channels.
For example, if you want to query slot 1, chann el 2 with the command,
“:SENSe[n]:[CHANnel[m]]:PO Wer:WAVelength?” on page 109, you should
send the command:
•:sens1:chan2:pow:wav?
Laser Selection Numbers
The laser selection number, [l], identifies the upper or lower wavelength
laser source for dual wavelength Laser Source modules and Return Loss
modules with two internal laser sources. The lower wavelength source is
denoted by1. The u pper wavelength s ource is denoted by 2.
The Agilent 8164A/B slot for a back-loadable tunable laser m odule is
numbered zero.
NOTE
The channel number of single channel modules is always one .
NOTE
If you do not specify a slot or channel number, the lowest possible number
is used as the default value. This means:
• Slot 1 for the Agilent 8163A/B and Agilent 8166A /B mainframes.
• Slot 0 for the Agilent 8164A/B mainframe .
• Channel 1 for all channels.
