General

RS232: 9-pin D-sub, three wire serial

∗1: All specifications apply when calibrated at ambient temperature after a five minute warm up.

∗2: In most applications, immunity is typically better because interferring signals are modulated and varying in frequency rather than being CW. Measurements

were made in CW mode by injecting a signal into the Site Master through a coupler.

∗3: Where υp is the cable’s relative propagation velocity. ∆ frequency is the stop frequency minus the start frequency (in Hz). Wide frequency sweeps improve

resolution but reduce maximum display range.

∗4: Where F

is the waveguide’s cutoff frequency (in Hz) and F

is the start frequency (in Hz). ∆ frequency is the stop frequency minus the start frequency (in

Hz). Wide frequency sweeps improve resolution but reduce maximum display range.

InstaCal

Module ICN50

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.

∗The InstaCal

Calibration Module exhibits slightly degraded directivity performance com-

pared to precision loads. Users having applications that require DTF-RL measurements

> | 38 dB | may want to consider using precision load calibration components in place of the

InstaCal calibration module for greater measurement accuracy.

∗2: In most applications, immunity is typically better because interferring signals are modulated and varying in frequency rather than being CW. Measurements

were made in CW mode by injecting a signal into the Site Master through a coupler.

∗3: On-Frequency interference immunity is specified to within +10 kHz of the carrier frequency.

∗4: On-Channel interference immunity is specified to within 1 MHz of the carrier frequency.

∗5: Where

is the cable’s relative propagation velocity. ∆ frequency is the stop frequency minus the start frequency (in Hz). Wide frequency sweeps improve

resolution but reduce maximum display range.

∗6: Calibration stored with instrument configuration.
