4 Connect the RF output of the 83712B to the channel 2 input of the DCA.
DCA Setup:
5 Push the default setup button.
6 Turn off all channels except for channel 2.
7 Turn on averaging to 64.
8 On 86100C instruments, set the trigger source Front panel, DC–3.2 GHz. On 86100A/B
instruments (serial prefix below US4051), set the trigger source Front panel, DC–2.5 GHz. On
86100A/B instruments (serial prefix US4051 and above), set the trigger source Front panel, DC–
2.75.
9 For the trigger, set normal Hysteresis, and positive trigger edge.
10 Set the vertical scale to 20 mV/div and the vertical offset to 0 mV.
11 Set channel 2 to the 20 GHz bandwidth setting.
12 Turn on the period measurement function.
8133A Setup:
13 External trigger input with 100 ns period.
14 Set channel 2 output to +2.5V square wave with 0V offset.
15 Enable channel 2 output and disable all other outputs.
Take Measurements:
16 For each data point do the following.
a Set the 83712B to the appropriate frequency and power.
b Set the Horizontal Scale as appropriate.
c Set the Horizontal Delay as appropriate.
d Measure the period.
17 Repeat Step 16 for all data points.
18 Compare each data point with the test line limit listed.
19 All data points must be within specifications for the test to be a pass.
