Analog Outputs
The transmitter provides sample signals that let you monitor performance. The sources of these analog
outputs are pre-defined and are not user-configurable.
See Table 1.8.5 for a list of these outputs, their descriptions and their associated output pins on the
REMOTE I/O-B (J6B) 25-pin female D-sub connector on the control/interface PWB (A4). The outputs are
op-amp buffered outputs from a digital-to-analog converter (DAC) on the control/interface PWB. The dc
voltage of each output is between 0 and a maximum of 6 V, and varies linearly within the real limits of
the parameter being monitored. The monitoring circuit’s impedance for each analog output must be
greater than 1,000 ohms.
Ground/shield connections are available on pins J6B-5, 10, 15, 20 and 25.
Nautel provides a D-sub mating connector (Nautel Part # JS31) and connector shell (Nautel Part # JS35)
in the ancillary parts kit to facilitate customer connections to the control/interface PWB.

ANALOG OUTPUT DESCRIPTION OUTPUT PIN
Forward Power Reports a sample of the transmitter’s forward power level. This dc voltage
is a square law function and will be full-scale (6 V) when the forward
power is 5 kW.
J6B-21
Reflected Power Reports a sample of the transmitter’s reflected power level. This dc voltage
is a square law function and will be full-scale (6 V) when the reflected
power is 800 W.
J6B-22
B+ Voltage Reports a sample of the B+ dc voltage level. This dc voltage is a linear
function and will be full-scale (6 V) when the B+ voltage is 400 V.
J6B-23
Dc Current Reports a sample of the transmitter’s dc current level. This dc voltage is a
linear function and will be full-scale (6 V) when the dc current is 25 A.
