Agilent Technologies 856290216 service manual TAM Requirements

nAfter the power-on self-realignments are complete, press PASS CONTROL . This removes the computer as being the active controller on HP-IB, permitting the TAM to be the active controller.

nThe TAM functions are now available and are listed, along with any limitations. For example, if Automatic Fault Isolation were selected from the Diagnostics Menu, the ID string would be changed to HP8561E. For an HP 85613, all TAM diagnostics can be used on an HP 85623, except for Manual Probe Troubleshooting.

You can now execute any of the TAM functions listed without further computer interaction.

nPress NNSNNN CONTROL to execute an unlisted TAM function. This changes the ID string in EEROM back to HP8562E, and shows the complete menu of available TAM functions.

Note	The analyzer will always behave like the model number emulated from the last
	TAM function, even though the ID		string in the EEROM was changed back
	to HP8562E. The analyzer	will not	revert back to an HP 85623 until power is
	cycled, but that is not yet	necessary.

nBefore exiting the TAM I/F SW program, press RESTORE DUT IDS; .

Note	The amount of free disk space for the system mass storage file location will
	decrease over time, since a data file is created for each HP 85623 used with
	this program. Once a repair is completed for a given HP 85623, its associated
	data file can be purged. A good rule of thumb is to purge any data file which
	is more than 1 month old.

TAM Requirements

For the TAM to function properly, certain parts of the spectrum analyzer must be operating properly. These include the CPU, parts of the program ROM and program RAM, the keyboard and keyboard interface, and the display.

Even though the TAM communicates to the operator via the display, some display problems can be troubleshot using the TAM. This is possible by using the Print Page softkey. Even if

the display is dead, Print Page is still active. Refer to Chapter 13, “Display/Power Supply Section,” for instructions on using the TAM when the display is not functioning.
