System Operational Checks
The following procedure will confirm that the RF interface cables between
the Test Set and analyzer are installed and the system is working correctly.
Before beginning this procedure complete the following steps:
•
Stack the analyzer system for the 24-Port System.
• Install the two Test Set I/O cables on the U3022BH10 rear panels.
•
Install all of the RF interface cables (U3022-20214) as shown on the front panel.
• Install the included female 3.5 mm short (85052-60007) to Port 1 on the analyzer.
Equipment Setup
• Turn on the test sets and analyzer.
• Preset the analyzer and make the following settings:
— Set to Multi-Port Mode. Use Test Set file: U3022BH10_x2_pnax_p4
— Frequency range: 10 MHz to 18 or 26.5 GHz
— IFBW: 1 k Hz
— Scale: 20 dB/ Div
— Set the PNA to measure S11
— Ensure the RF path of the analyzer is in Default mode. Refer to
Figure 43, "RF Path Configuration” on page 51.

The 3.5 mm short will be relocated to each Test Port and an uncorrected reflection
response trace should be displayed that resembles the following plots indicated in
the tables that follow. If you suspect an RF signal path problem, refer to the RF
cable diagram and check the interface cables associated with this signal path for
proper installation.
