●Features a high-brightness 8.4-inch LCD display that is easy to read in any lighting conditions.
●Measurement speed has been increased, enabling measurements approximately twice as fast as the S331D.
●Equipped with a USB interface that supports USB memory devices and USB sensors.
Measurement items: Return loss, cable loss, DTF, phase
2-port transmission measurement: High/low output
Sweep speed: 1 ms per data point (typical)
Display: Single and dual measurement touchscreen
Calibration: OSL, InstaCal, FlexCal
Bias tee: 32 V internal
■Return Loss, VSWR
The Site Master can measure return loss and VSWR to verify compliance with antenna system specifications.
■Cable Loss
Cable loss measurement measures losses in a cable feed system. Before installation, this measurement can be verified by accessing both ends of the cable. It also automatically calculates average cable loss.
■Fault Location Detection
Return loss measurement is the best way to check system integrity. The fault location detection (DTF) function is used to troubleshoot the system and identify problems.
Site Master DTF measurements use a fast Fourier transform to convert frequency data into time-domain data, then display the results as distance. Common trace math functions can be used to monitor small relative changes.
■Transmission Measurement Function (Option 0021)
Cellular/PCS and 3G base stations now use diplexers, duplexers, and tower-mounted amplifiers to expand coverage. The Site Master's transmission measurement function can measure their gain, isolation, and insertion loss, as well as isolation between sectors.
■Internal Bias Tee (Option 0010) *Requires Option 0021
The internal bias tee can be switched on as needed to supply +12 V to +32 V to the RF center conductor of the port, eliminating the need to bring an external power supply into the field.
