VXI 3002 manual RF output, Specification, Test equipment, Store/Recall Address

TEST PROCEDURES

Each test procedure relies on the UUT being set to its power-up conditions. Reset the UUT after each test procedure by setting:

Store/Recall Address 999

Recall

At the end of this chapter are a set of results tables which give all the test points for each of the tests. These tables should be photocopied and used to record the results of all the measurements taken.

RF output

Specification

Range		−137 dBm to +25 dBm (+19 dBm above 1.2 GHz).
		When AM is selected, the maximum RF output level decreases linearly with increasing
		AM depths to +19 dBm (+13 dBm above 1.2 GHz) at 99% depth.
Accuracy
				Accuracy over temperature range 17°C to 27°C
					9 kHz to 1.2 GHz	1.2 GHz to 2.4 GHz
				>−127 dBm	±1.0 dB	±2.0 dB
				Temperature coeff. over temperature range 0°C to 55°C
					9 kHz to 1.2 GHz	1.2 GHz to 2.4 GHz
					<±0.02 dB/°C	<±0.04 dB/°C
VSWR
		For output levels less than −5 dBm output VSWR is less than 1.3:1 for carrier
		frequencies up to 1.2 GHz and less than 1.5:1 for carrier frequencies up to 2.4 GHz.
Output impedance		50 Ω SMA female connector to MIL 390123D.
