Note

CONDITIONS files used with the operation verification software for either the

 

HP 8560 A/B-Series spectrum analyzers, or the HP 8560 E-Series spectrum

 

analyzers are not compatible with the frequency response adjustment software.

 

If the software is stored on an HFS-formatted hard drive, the frequency

 

response adjustment software and operation verification software should be in

 

separate directories.

 

 

When running the frequency response adjustment program in the future, set the system mass storage file location to read the disk where the CONDITIONS file is located and press Load Conds . If the CONDITIONS file resides on the default system mass storage file location, the CONDITIONS file is loaded automatically the next time the program is run.

The default system mass storage file location is : ,700,l. For the HP 9000 Model 236 (HP 9836), it is necessary to use an external disk drive. The disk drive must support double-sided format.

Getting to the Adjust Menu

Once all necessary items in the Conditions Menu are selected, you can run an adjustment by pressing Adjust Hem. Before the Adjust Menu is displayed, these things occur:

nAppropriate power sensor data files are loaded.

nHP-IB is checked for a response at each address.

nSerial and model number of the spectrum analyzer under test are queried.

Refer to “Adjust Menu” in this chapter for more details on running the adjustments.

Verifying the HP-IB

To see which test equipment responds on HP-IB, press Verify Bus . This check only verifies that there is a response at the address listed; it cannot tell that a particular piece of equipment is at a particular address. This is useful for verifying HP-IB connections without entering the Adjust Menu.

Querying the Spectrum Analyzer Serial Number

The frequency response adjustment program automatically queries the spectrum analyzer serial and model number on three occasions: at program initiation, when loading the CONDITIONS file, and when entering the Adjust Menu. To query the analyzer serial and model numbers at any other time, press Query DUT S/a . This is helpful for adjusting multiple spectrum analyzers; you do not have to reload the CONDITIONS file or restart the program.

Exiting Frequency Response Adjustment

Press Exit Program to exit the frequency response adjustment program.

Dual-Bus Operation

The frequency response adjustment program may be used on dual HP-IB systems, such as the microwave test set. In these systems, all the test equipment is connected to HP-IB at select code 7, and the device under test (for example, the spectrum analyzer) is connected to HP-IB at select code 8.
