HP 11807A,E Software
HP 11807A,E Software
The HP 11807A,E Option 001 Software performs fast, accurate, automated tests
that determine the RF and audio performance of FM radios. The measurement
methods and specifications used for these tests are based on methods and values
derived from the following industry standards:
EIA/TIA-603
EIA/TIA-204-D (TEST_19)

• External power supply An external power supply for the FM radio can be configured to
the HP 8920A in one of three ways:
1. A power supply or battery can be connected directly to the FM radio.
2. A power supply can be connected to the rear-panel DC CURRENT MEASUREMENT
banana-plug connectors. (This requires the HP 8920A Option 003, HP-IB/RS-232/
Current Measurement.)
3. A power supply can be controlled by the HP 8920A when it’s connected to the HP-
IB connector. (This re quires the HP 8920A Option 003, HP-IB/RS-232/D C Current
Measurement.)

NOTE: The firmware revision A.14.00 in the HP 8920A,D had several enhancements, which are
standard in the HP 8920B. This chapter applies to users with:
• HP 8920A test sets with firmware revision above A.14.00
• All HP 8920B test sets.
The test set’s firmware revision is displayed on the top right corner of the
configuration screen.
• Press SHIFT CONFIG to display the configuration screen and read the firmware
revision.
If you have an HP 8920A test set with firmware revision below A.14.00, refer to
chapter 3, "Using the Software/HP 8920A FW Rev. Below A.14.00," on page
57. Contact Hewlett-Packard at 1-80 0-922-8920 for details on upgrading your

• The software has already been customized and saved to a memory card
Customize the software:
• Decide which te sts you desire to run (Order of Tests)
• you may want to run all, some, or just one of the tests.
• Specify which channels to test (Channel Information)
• you may want to test one, some, or all of the channels on your radio.
• Change the pass/fail limits for specific measurements (Pass/Fail Limits)
• you may want the pass/fail limits to have tighter or looser specifications than the
default settings.
• Change the test environment and conditions (Test Parameters)
• decide output format.
• enter specific information about radio equipment and/or environment.
• Save any or all of the above customized changes to a memory card (Save/Delete
Procedure)
Set Up Test Set:

Testing Overview
Selecting a Test Procedure
To load the software , you must f irst se lect the location to load fr om (in th is case, i t
will be
Card) and a procedure filename. Your card comes pre-programmed with
at least one procedure. The actual software program does not get loaded into the
test set’s m emory until k1 (
Run Test) is selected. It will take approximately 15
seconds to load the software in an HP 8920B, and approximately two minutes in
an HP 8920A,D.
The software memory car d can be removed after the program is loaded into the
test set’s memory. The program will remain in memory after a power-down/
power-up cycle, unless it is manually deleted or a new program is loaded.
When tests begin to run, they are execute d in the order in whi ch they were entered
into the Test Procedure.
Pressing CANCEL will pause the current test (press k2 to continue the test.)
