Instrument
Configuration
This setup procedure uses Option 010, network switch and cables,
for LAN communication without connecting to an existing
network. For other types of communication connections, see the
PSA
EMI Measurement Receiver Guide. If you are going to connect
through an existing network, check with your IT department for
any additional requirements.
This Quick-Start guide assumes the use of the N5181A signal
source. If you are using another source, see the PSA EMI
Measurement Receiver Guide for more information.
The following instruments are required to configure a CISPR–16
compliant measurement receiver:
• N5181A, N5182A, 8648B, E4438C, or E8257D signal source
The signal source is used only during system alignment.
• PSA Series Spectrum Analyzer
— Serial Prefix of US4430, MY4430, SG4430 or greater
— Firmware version A10.xx or later
• N9039A RF Preselector
1. Stack the instruments as shown in the following graphic:

the RF Preselector’s front panel) to turn the RF Preselector on.
NOTE Allow the RF Preselector to warm-up for 30 minutes before
making a calibrated measurement. To meet its specifications, the
RF Preselector must meet the operating temperature
requirements.
8. If you have previously turned on the RF Preselector, skip the
rest of this section and go to “Instrument Communication” on
page 9.
