SDI7 module adjustment procedures
Set up the digit
al signal analyzer.
CAUTION. Electrostatic discharge can damage the oscilloscope modules. To
prevent damage, always work in a static free environment and discharge the
static voltage from your body by wearing a grounded antistatic wrist strap while
handling these modules.
1. Install the 80A03 output cable into the Channel 1/2 slot of the oscilloscope.
2. Install the 80E04 sampling head into the 80A03 adapter and connect the two
using the SMA cables.
3. Install the TCA-75 into the left port of the 80A03.
4. Install the TCA-BNC into the right port of the 80A03.
5. If neede
d, press the Default Settings button o n the oscilloscope.
6. Press the Channel 1 button on the 80E04 sampling head to activate Channel 1.
Part B: Characterize the test system.
1. Connect the equipment as follows:
a. AFG3101 output to 1 m high bandwidth cable.
b. The other end of the cable to a TCA-75.
c. The TCA-75 to the 80A03 in the o scilloscope and plug-in.
d. A50Ω cable from the AFG3101 trigger output.
e. The
other end of the 50 Ω cable to the BNC to SMA adapter.
f. TheSMAadaptertothe6dBpad.
g. The 6 dB pad to the trigger direct input on the oscilloscope.
2. Keep the AFG3101 at the same o utput as in Part A of this test.
3. Set the oscilloscope:
Time/Div: 20 μs
Volts/Div: 50 mV
Averaging: 16
Record Length: 4000 points
4. On the oscilloscope, select measurement 1 and then pulse amplitude and
select it to measure Cycle RMS.
5. On the oscilloscope, select measurement 2 and then pulse amplitude and
select it to measure Cycle Mean.
