Performance Verification
Pattern Lock Check, 86100C Option 001
8133A Setup:
8 Set the trigger output to 0.5V amplitude.
9 Set the Channel 2 amplitude to 0.5V.
10 Set the frequency to 3 GHz.
11 Enable the channel 2 output and trigger output. Disable all others.
12 Set the bit pattern to the following.
• Bits: 32
• Pattern: 1101 1110 1000 0100 0100 0111 0101 1001
N O T E Spaces in the bit pattern are inserted to make it easier to read the numbers.
Take Measurements:
13 For each data point listed in
14 Set the 8133A to the listed pattern length and frequency.
15 Set the DCA Data Rate and Pattern Length; Relative Bit to 1.
16 Measure the time reference of the first rising edge and adjust the delay to this value.
17 Setup a histogram window with the following parameters:
• Centered around [Edge delay +.5*(1/freq)]
• X1 and X2 positions are ±0.02*(1/freq)
• Y1 and Y2 positions are ±400 mV
18 Wait 5 seconds to collect the data and then read the Standard Deviation of the histogram.
19 Compare to the Test Limits listed above.
20 Repeat
21 Compare each data point with the Test Limits. All data points must be a pass for this test to pass.
