OUT10G1 Board for
Standard models
The OUT10G1 board provides analog and marker outputs to the front-panel
connector. Amplitude, filter, offset, and On/Off controls are added to the analog
outputs. High/Low voltage and On/Off controls are added to the marker outputs.
The OUT10G1 board consists of the following blocks:
„
Analog output amplifier
„
Marker output driver
„
Selectable low-pass filter
„
Selectable attenuator
„
Voltage monitor
„
Controller PLD
OUT10G2 Board for
Option 02/06
The OUT10G2 board uses the same raw board as the OUT10G1 board. The
difference is that the OUT10G2 board has no analog output circuitry. For Option
02 and Option 06, the analog signal path is on the relay module. The OUT10G2
board has an analog voltage monitor. The OUT10G2 board consists of the
following blocks:
„
Marker output driver
„
Voltage monitor
„
Coax switch driver
„
Controller PLD
Relay Module (Option 02
and Option 06 only)
The relay module provides switches for analog outputs. For Option 02, the relays
switch the analog outputs on and off. For Option 06, the relays switch the
interleaving and the analog outputs on and off. An RF power combiner is used for
mixing channel 1 and 2 signals. The output of the power combiner goes to the
Interleave output.
