System Operational Check
System Operational Check
The following procedure will confirm that the RF interface cables between the test
set and analyzer are installed and the system is working correctly. Ensure that your
analyzer is calibrated by measuring the short on each port before connecting the test
set.
Before beginning this procedure you should complete the following steps:
• Stack the analyzer on top of the test set.
• Install the Test Set I/O cable on the rear panel.
• Install all of the RF interface cables 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 set and network analyzer.
• Preset the analyzer and complete the following settings:
— Set to Multi-Port Mode
— Frequency range: 10 MHz to 20 or 26.5 GHz
— IFBW: 1 kHz
— Scale: 10 dB/Div
— Set the PNA to measure S11
— Ensure the RF path of the analyzer is in Default mode. Refer to “RF Path
Configuration with Option 029” on page 4 2 .
Verify Results
The 3.5 mm short will be relocated to each Test Port and an uncorrected Sxx
reflection response trace should be displayed that resembles the following plots
indicated in the table below. 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.
The trace ripple (peak-peak variation will be higher than when using an ECal Module
due to variation in your Short’s performance. If response is in question perform
“Cal
Kit Operational Check” on page 6 0 .
