Agilent 81133A / 81134A Performance Verification

Agilent 81133A / 81134A Performance Verification, December 2003

12 Set up the Digitizing Oscilloscope Agilent 54121T:

• Press [AUTOSCALE]

• Select the Display menu and set the Number of Averages to 64

• Select the Channel menu and set the Attenuation factor of channel 2 to

• Set the VOLTS/DIV of channel 2 to 10 mV/div, the OFFSET to 500 mV

• Select the Timebase menu and set the TIME/DIV to 10 ps/div

13 Center a positive edge of the signal

14 Press [MORE] and [HISTOGRAM]

• Select the Window submenu and set:

• Source is channel 2

• Choose the Time Histogram

• Press [WINDOW MARKER 1] and set it to 490 mV

• Press [WINDOW MARKER 2] and set it to 500 mV

15 Select the Acquire submenu, set the Number of Samples to 1000 and

press [START ACQUIRING]

16 After the data for the time histogram has been acquired (#Samples =

100 %) select the Result submenu

17 Press [MEAN] and [SIGMA]. Record the values of sigma as the RMS

jitter.

18 Check the data jitter at the following frequencies:

Frequency Acceptable Range TR Entry

100 MHZ < 4 ps 4-5

1 GHz < 4 ps 4-6

2 GHz < 4 ps 4-7

19 Set the Channel Frequency Divider of the 81133A/81134A to 2 and

check the data jitter at 3 GHz. Record the result in TR Entry 4-8.

For the 81134A repeat the tests for channel 2.
