Agilent Technologies 856290216 Sensor, , Utilities,

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

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

operation 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.
