Installation and Setup
Firmware Revision
readily available. You can also obtain the firmware revision and serial
number by pressing System, More, Show System.
❏ Allow the analyzer to warm-up for 5 minutes before making a calibrated measurement.
To meet its specifications, the analyzer must meet operating temperature conditions.
If the analyzer is an Agilent Technologies E4402B, E4403B, E4404B, E4405B, E4407B,
or E4408B, connect a BNC cable from the AMPTD REF OUT to INPUT 50
Ω using an
adapter. After a 5 minute warm-up, press
System, Alignments, Align Now, All.
CAUTION When operating in dc coupled mode on analyzers with Option UKB ensure
protection of the input mixer by limiting the input level to 0 Vdc, +30 dBm.
When operating in ac coupled mode, ensure protection of the input mixer by
limiting the input level to 50 Vdc, +30 dBm.
NOTE It is normal to hear clicking when the Auto Alignment function is on. See
“Running Internal Alignments” on page 18 for more information.
Why Aren’t All the Personality Options Loaded in Memory?
Many measurement personality options are available for use with this instrument. If the
option is loaded in the instrument, you must also have a license key entered, to use it.
Some versions of instrument hardware my not have enough memory to accommodate all
the options that you have ordered. If this is the case you will need to swap the applications
in/out of memory, as needed. It may also be possible to upgrade your hardware to have
more memory. Contact your local sales/service office.
Using an External Reference
If you wish to use an external 10 MHz source as the reference frequency, connect an
external reference source to the
10 MHz REF IN connector on the rear panel. The signal level
should be greater than –15 dBm.
NOTE It is not necessary to connect the 10 MHz REF OUT to the 10 MHz REF IN on
the rear of the analyzer. Doing so results in a “Frequency Reference Error”
message.
1. To use an external frequency reference, connect it to the EXT REF IN connector on the
rear panel (see “Rear-Panel Features” on page 33).
Firmware Revision
To view the firmware revision of your analyzer, press System, More, Show System. If you
call Agilent Technologies regarding your analyzer, it is helpful to have this revision and the
analyzer serial number available.
