Installation and Setup

Turning on the Analyzer for the First Time

If using LAN, set the IP address of the analyzer to an appropriate number for your network (one that the network recognizes, but that is not yet in use):

Press System, Config I/O, and note the IP address.

If the current address is not appropriate, press IP Address and use the keypad to change it.

Connect the LAN cable to the LAN connector located on the rear panel of your analyzer (see “Rear-Panel Features” on page 27).

Cycle the analyzer power.

NOTE

It is necessary to cycle the power to the analyzer after plugging in the LAN

 

for the analyzer to recognize the network.

 

 

Allow the spectrum analyzer to warm-up for 30 minutes before making a calibrated measurement. To meet its specifications, the analyzer must meet operating temperature conditions.

NOTE

It is normal to hear clicking when the Auto Alignment function is on. See

 

“Running Internal Alignments” on page 16 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

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 27).

2.Enter the frequency of the external reference into the analyzer:

a.Press System, Reference, Freq Ref

b.Select the Ext function.

c.Use the keypad to enter the frequency of the external frequency reference.
