CASE LID - METER AND I/O PANELS
The Meter and I/O Panels, mounted on the inside of the case lids, are used for monitoring multi-
channel signals. While these panels are not required for receiver operation, they provide more
versatility in the field. Each GDP-32
II
is configured with an appropriate Meter and I/O panel
based on the number of channels specified at purchase.
Figure 2.3(a) shows a small case 2-channel Meter Panel. Figure 2.3(b) shows a large case 16-
channel Meter Panel. Figure 2.3(c) shows the large case 8-channel combined meter and
input/output panel.
1. Analog Meters
Zero-center. ± 5 volt analog meters monitor analog channel output. The meters are used
to determine SP levels at all frequencies, and to monitor signals at frequencies below 1
Hz.
2. BNC Output Jacks
Output jacks direct the signal to an external device (e.g. oscilloscope). The output jacks
are connected to the channel select switches on the I/O panel. The monitored signal is
identical to the signal presented to the ADC on each analog board.
3–4.Channel A and B Selectors
Select the channels for Meters A and B to monitor.
5. Analog Input Port
This 9-pin “D” connector connects the meter panel with analog voltages from the main
chassis.
6. Channel Input Connectors
The analog binding posts provide a convenient method for connecting up to eight receiver
channels to external signals.
7. MS Connector Cable
Connector cable for attachment to the Analog I/O panel.
8. Ground Jacks
An analog ground reference post and a case ground jack.
