HIGH LEVEL NOISE
TEST
The following test verifies that the transmission high-level noise in the
371XXC Millimeter VNA System will not significantly affect the accu-
racy of subsequent measurements. High-level noise is the random
noise that exists in the 371XXC Millimeter VNA System. Because it is
non-systematic, it cannot be accurately predicted or measured. Thus,
it cannot be removed using conventional error-correction techniques.
Measurement calibration is not required for this test.
NOTE
This test is not applicable if you are only using a single
3740A-X module on
Port 1
.
Test Setup
Set up the 371XXC Millimeter VNA System controls as shown at left.
Test Procedure
The test procedure is described below.
.Step 1
Connect the two modules together.
.Step 2
If using two 3740A-X’s, press
Ch1
key and perform
steps 3 through 9. Otherwise, go to step 10.
.Step 3
Press
Trace Memory
key.
