MULTI-PURPOSE PROBE

- Because the two coaxial connectors are coupled and because any signal connected to one of the
ports will be seen at the other port, it is not advisable to connect two different signals to ports A
and B at the same time.
- The 100 MHz Baseband Upconvert option mixes the signal with a 100 MHz signal for analyzing
baseband (see page 97).
CCP (Carrier Current Probe)
The CCP (Carrier Current) input can be used to test for carrier current signals on any pair of conductors
less than 250 volts. Before testing an unidentified pair of power conductors, a voltmeter should be used
to measure the voltage across the conductors. If this voltage exceeds 250 volts, do not test with the
MPP.
To measure carrier current with the MPP:
1. Ensure that the battery level of the OSCOR
is enough to power the unit.
2. Remove the power cord from the AC adapter used to
power the OSCOR unit.
3. Plug the power cord into the Carrier Current Input on the MPP.
4. Plug the other end of the power cord into the outlet you wish to check.
5. On the OSCOR unit, make sure that the “CCP (Carrier Current)” input is selected. The options for
CCP testing will appear on the right side of the MPP tab.
6. Measurements can be made with three different pair configurations: Hot/Neutral,
Neutral/Ground, and Hot/Ground.
7. To automatically switch between all three different pair configurations, select “Enable Auto
Sequencing.” The MPP will automatically rotate through the pair selections after a few seconds
each.
