Agilent 8753ES System Verification and Performance Tests
8. Test Port Crosstalk
Perform this test to measure the maximum level of signal leakage between the analyzer’s
test ports. Crosstalk is measured with shorts attached to the test ports after a
normalization measurement with a thru.
Analyzer warm-up time: 30 minutes
Specifications
Required Equipment
Procedure
Normalization from 300 kHz to 3 GHz
1. Connect the 24-inch cable between the analyzer’s test ports 1 and 2 as shown in
Figure 2-26. Use the appropriate cable for your analyzer (50Ω or 75Ω).
