Accuracy

The following procedure lets you measure the pulsed RF output level and CW output level and compare them to verify pulse leveling accuracy.

1.On the 682XXB/683XXB:

a.Press On/Off (Internal Pulse Status menu) to turn off pulse modulation.

b.Press CW/SWEEP SELECT to return to the CW Menu display.

c.At the CW menu, press Edit F1 and set F1 to the frequency noted in the Test Record.

2.On the Oscilloscope:

a.Adjust the vertical offset to place the trace ex- actly on the center graticule; this is used as the CW-level reference line.

b.Use the Auto Triggering mode to continue sweeping the display when the pulse is off.

c.Adjust the vertical sensitivity to the most sen- sitive setting (mV/div) possible while keeping the trace at the center graticule reference line.
