P6249 4 GHz 5X Active Probe Instruction Manual 41
Output Zero
Use this procedure to verify the probe output zero.
1. Connect the test equipment as shown in Figure 12.
2. Attach the probe to a TEKPROBE interface on the 1103 power
supply.
3. Ground the probe tip by connecting the probe tip to the probe
ground socket. (Connecting two KlipChip adapters together is
recommended.)
4. Set the 1103 offset VAR/0V to 0V.
5. Observe the multimeter display and record the results on the test
record.
The displayed DC level should be 0.00 V ±10 mV.
