Lambda Scan Applications

Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition

Lambda Scan Applications

These functions combine multiple SCPI commands into a single, functional
operation. They are designed to allow quick and easy access to common
instrument command sequences.
These application functions allow you to perform one of the following
applications:
• A Lambda Scan - a Lambda Logging operation where an Agilent
8164A/B Lightwave Measurement System with a back-loadable
Tunable Laser module and up to four Power Meters installed, performs a
wavelength sweep where the Tunable Laser module and Power Meters
are coordinated with each other.
• A Multi Frame Lambda Scan - a Lambda Logging operation where an
Agilent 8164A/B Lightwave Measurement System with a back-loadable
Tunable Laser module performs a wavelength sweep and the Tunable
Laser module is coordinated with Power Meters that are installed in the
mainframe and in other mainframes. These mainframes must be
connected to the GPIB bus and have their Input Trigger Connector
connected to the Output Trigger Connector of the Agilent 8164A/B
Lightwave Measurement System mainframe.
The following two functions apply to both Lambda Scan and Multi Frame
Lambda Scan applications:
• The Set Lambda Scan Wavelength
(hp816x_set_LambdaScan_wavelength) function allows you to use a
different wavelength than 1550 nm during a Lambda Scan operation. All
Power Meters taking part in the Lambda Scan operation will be set to
the chosen wavelength.
• The Enable High Sweep Speed (hp816x_enableHighSweepSpeed)
function enables/disables the highest available sweep speed (40
nanometers per second) for Lambda Scan operations. The Lambda Scan
operation chooses the highest possible sweep speed for the chosen
step size.
• If you choose Enable, the highest sweep speed possible will be used.
This may lead to less accurate measurements.
• If you choose Disable, the highest sweep speed will not be used.
