To troubleshoot the system

Most system problems are caused by faulty cabling or switch configurations.

Refer to Figure 20 on page 53 and Figure 19 on page 51 and do the following:

✔Check system connections and settings:

1 system connections to the DUT

2 system interconnections

3 GPIB cabling

4 GPIB address settings

If the cabling and switch configurations are verified correct, do the following:

✔Complete the Agilent E8364B PNA Series vector network analyzer operator’s check in “Performing the RF Subsystem Functional Verification Test" on page 125.

✔Complete the Agilent 4156C precision semiconductor parameter analyzer self- test in “Performing the DC Subsystem Functional Verification Test" on page 121.

✔Complete the Agilent 4284A self- test by cycling the instrument’s line power. If errors occur, refer to Appendix B in the precision LCR meter operation manual. The operation manual is included in with the Agilent 85225F performance modeling system.

✔If you suspect trouble with the E2050B, see “Chapter 4 Troubleshooting” in the E5810A LAN/GPIB gateway installation and configuration guide.

✔Complete the Agilent E5250A self- test and leak test found in Chapter 3 of the low leakage switch mainframe user’s guide. The user’s guide is included with the Agilent 85225F performance modeling system.

If a problem with one of the system components is found, refer to the troubleshooting and repair information in the individual instrument’s product documentation.
