To run this program in a dual-bus configuration, enter equipment addresses as described in “Setting HP-IB Addresses” above, making sure that each address properly identifies the bus select code to which it is connected. Program operation is the same for dual-bus and single-bus configuration.

Sensor Utilities Menu

The frequency response adjustment program needs to know the cal factors of each power sensor being used. Create, edit, view, and delete data files containing cal factors for each power sensor in the Sensor Utilities Menu. Power sensor data filenames include the last five digits of the power sensor serial number. For example,

for HP 8481A power sensors the filename is SEN81NNNNN for HP 8485A power sensors the filename is SEN85NNNNN

where NNNNN represents the last five digits of the power sensor serial number (the serial number suffix). Note that the first two digits in the filename correspond to the last two digits of the power sensor model number.

All power sensor data files available on the system mass storage location file are listed upon entering the Sensor Utilities Menu.

Note

Power sensor data files created using the VERIFY-6XEoperation verification

 

software (for HP 856OE/6lE/62E/63E/64E/65E spectrum analyzers) are

 

compatible with the frequency response adjustment software.

 

 

Adding a Power Sensor Data File

To add a new power sensor data file, press Add File , and enter the power sensor model number as requested. An error message is displayed if a disk at the current system mass storage file location is not found.

When prompted for the power sensor serial number, enter only the last five digits (the serial number suffix). You are then prompted for a cal factor frequency and for the cal factor. These frequency/Cal-factor pairs need not be entered in order of increasing frequency; the program inserts the pairs in their proper place. All frequencies should be entered in MHz.

Note

To use the HP 8485A, it must have a calibration factor at 10 MHz. Standard

 

HP 8485As have calibration factors down to only 50 MHz.

 

 

A 50 MHz Cal-Factor must be entered in order to calibrate the power sensor. Some power sensors do not include a 50 MHz Cal-Factor on their chart or calibration record; it is listed as part of the Calibration Procedure on the case of the power sensor.

If a mistake is made entering a cal factor, enter the frequency of the erroneous cal factor at the next frequency prompt. Enter the correct cal factor at the next prompt. If an error was made entering the frequency value, enter the erroneous frequency at the next frequency prompt and a zero for the cal factor to delete that frequency point.

Once all cal factor data for a power sensor is entered, enter an S at the next frequency prompt. The power sensor data is then stored on disk.
