3.1.1.4 OSCILLOSCOPE
See Figure 3-6. This panel displays an oscilloscope to allow monitoring of audio input
parameters. The oscilloscope displays a real-time waveform for the selected audio input
(e.g., L/R audio input). The audio input(s) being monitored is displayed in the upper, left-hand
corner of the panel (e.g., R in green, L in blue for L/R audio input.) The limits for the
amplitude axis (volts/division) and time axis (microseconds/division) are preset in software for
each selected input and cannot be adjusted. The following button controls are available:
Use the “cog” button to access the measurement source setting (refer to the VS transmitter’s
Operations and Maintenance manual). Use the drop-arrow to select from the various options
- Precorrection Forward/Reverse (reverse and forward sample signals), MPX Audio,
Left/Right Audio (left and right signals) or Audio I/Q (shows I and Q signals).
NOTE
If the front panel UI’s test signal generator is enabled, the test signal may appear on certain
oscilloscope displays. To view the actual audio input’s signal, disable the test signal
generator (refer to the VS transmitter’s Operations and Maintenance manual).
