Installation

Test 7. I/Q Functionality

Description:

An internal I/Q calibration is performed using the E6432A Soft Front

Panel (SFP). The E6432A Option UNG is IQ modulated by an E4430B

Option UN8. A QPSK modulation format is used with a symbol rate of

2 MS/s and a root Nyquist filter with an alpha of 0.5. The occupied

bandwidth is then, 1.52 MHz or 3 MHz. The bandwidth is measured

with a spectrum analyzer.

Equipment Required:

8563E spectrum analyzer

E4430B Option UN8

Equipment Setup:

NOTE All test equipment requires a 30 minute warm up period to ensure

warranted performance. The E6432A needs to have an external 10 MHz

reference connected. Ensure the external 10 MHz reference is selected

in the configuration pull down menu.

Connections

1. Use a high frequency 3.5 mm cable to connect the E6432A output to

the input of the 8563E.

2. Connect BNC cables from the E4430B rear panel I and Q outputs to

the E6432A front panel I and Q inputs.
