Setting Up the System
Setting the GPIB Address
5.1 Setting the GPIB Address
To set the GPIB address of the attenuator
1. Press S
YST.
2. Edit the value for ADDRESS using the Modify keys.
Resetting the GPIB Address
To reset ADDRESS, press and hold SYST until the value resets (this
takes approximately two seconds).
ADDRESS resets to 28.
5.2 Selecting the Wavelength Calibration and Its
Function
The attenuation at any point on the filter is wavelength dependent.
This dependence is measured and stored in the instrument, and is
used, with the value for the wavelength entered by the user to
compensate for the dependence. This is the wavelength calibration
data.
As well as the wavelength calibration data measured for and stored
in your instrument in the factory, there is space reserved in memory
for a set of your own user calibration data.
There are two choices concerning the use of wavelength calibration
data.
• Whether or not the data should be used to position the filter to
compensate for wavelength dependence.
• Whether the factory-made wavelength calibration data is used,
or the data entered by the user.
