TekProbe Communication
This procedure verifies the operation of the TekProbe III interface.
1. Turn on the oscilloscope. Wait for the power up self test to
complete.
2. Disconnect all cables or probes from the inputs.
3. Press the Autoset button.
4. Press the CH 1 button.
5. Use the Vertical Scale knob to set the vertical scale factor to
100 mV/div.
6. Press the Vertical Menu button.
7. Attach the probe to the CH 1 input.
8. Select the Coupling menu.
9. Verify that AC and DC coupling and GND are selectable by
switching between them.
10. Verify that the channel 1 scale factor is selectable from 10mV/div
to 100V/div.
11. Verify that the Bandwidth is selectable between Full, 20MHz and
150MHz (2nd button along lower bezel).
DC Offset
This procedure verifies that the oscilloscope can compensate for the
DC offset of each volts/division range of the the P6339A probe.
1. With the probe attached to channel 1, set the oscilloscope to the
lowest volts/division setting (10 mV/div).
2. Set the input coupling to GND and set the ground reference to
center screen.
3. Install a retractable hook tip and ground lead on the probe head.
4. Short the input of the probe to probe ground by connecting a
short jumper from the hook tip to the ground lead.
5. Set the coupling to DC.
