Characteristic Checked

 

 

 

Equipment Required

A 50*W coaxial cable, 50*W termination, BNC+to+dual banana

 

adapter, and a digital multimeter ￿DMM￿.

 

 

Prerequisites

The AWG2021 meets the prerequisites listed on page C+5.

 

 

1.Use the test hookup and test equipment settings from previous check, however, add a 50 W termination at the DMM input.

2.Check offset accuracy:

￿Push the AWG2021 MANUAL TRIGGER button, and check that the displayed step is Step 5.

￿Check that the DMM voltage reading is in the range from 2.470 V to 2.530 V.

￿Push the AWG2021 MANUAL TRIGGER button, and check that the displayed step is Step 6.

￿Check that the DMM voltage reading is in the range from ±0.005 V to 0.005 V.

￿Push the AWG2021 MANUAL TRIGGER button, and check that the displayed step is Step 7.

￿Check that the DMM voltage reading is in the range from ±2.470 V to ±2.530 V.

3.Check Option 02: If the AWG2021 has Option 02, repeat the Gain Accuracy and Offset Accuracy Checks for the AWG2021 channel 2 (CH2).

4.End procedure: Disconnect the DMM.
