OSCOR Unit Operations with the MPP connected

Most of the OSCOR operations continue to operate with the MPP just as they do with the built-in
antenna panel. The maximum frequency range will automatically be adjusted for whichever MPP input
is selected; however all the other functions will operate the same. You can use the preamp or
attenuators, narrow in on specific frequencies, save a peak trace, look at an average trace, turn on detail
zoom, and generate a signal list. If a signal is detected, you can go to analyze mode and even
demodulate any analog signals that might be present.

Caution: Switching between MPP inputs will clear the peak trace. Be sure to save the peak trace before
switching probes for any data you wish to keep.

Selecting an MPP Input

Only one sensor or antenna on the MPP can be active at any given time. To activate a sensor or
antenna, select it from the list in the MPP tab by tapping it with the stylus.

After selecting an input from the list in the MPP tab, options for that input will be displayed on the right
side of the MPP tab. Options vary according to the selected input.
