SITE MASTER OPTIONS AND ACCESSORIES
RF Power Monitor (Option 5)
The optional RF Power Monitor features precision, high return loss
(low SWR) detectors. This excellent impedance match significantly
reduces the largest component of power measurement error,
mismatch uncertainty. Display formats include absolute power (dBm
or Watts) and relative power (dBr or %). Built-in Auto-Averaging
automatically reduces the effects of noise while zeroing control allows
optimum measurement accuracy at low power levels.
InstaCal
™
Calibration Module*
The InstaCal calibration module is available for all one-port
Site Master models (S113C, S114C, S331C and S332C).
With InstaCal, users can cut the time required to calibrate
the Site Master by as much as 50%. Moreover, InstaCal
reduces the potential for calibration error. With discrete
calibration components users are required to connect,
disconnect, and reconnect the various calibration
components during the calibration process, which greatly
increases the potential for calibration/measurement error.
With InstaCal, users are only required to connect the
InstaCal calibration module once – the calibration process
sequences automatically, ensuring an accurate calibration
of the Site Master. The benefit is calibrated measurements in
much less time.

Accessories
Calibration components
mate directly to a variety of
commercial and standard
military flanges – eliminating
the necessity of bulky,
precision waveguide
couplers. A few examples
of waveguide adapters are
35UA187N, 35UM40N, and
35UM58.
Bias Tee (Option 10A-S251C Only)
The optional bias tee is integrated inside the Site Master and
is designed for applications where both DC and RF signals
must be applied to a device under test, such as a tower
mounted amplifier (TMA). DC voltages of up to 15 volts at
0.24 amps may be applied to test devices with negligible
effect on RF performance as an RF input DC block isolates
the input port from the applied bias voltage.

Module ICN50
*The InstaCal
™
Calibration Module exhibits
slightly degraded directivity performance
compared to precision loads. Users having
applications that require DTF-RL measure-
ments >
38 dB
may want to consider
using precision load calibration components
in place of the InstaCal calibration module for
greater measurement accuracy.
