16、Difficult test specifications are easy to verify.The S800 series improves quality and reduces maintenance expenses by providing vector corrected calibration and a convenient user interface.These new microwave Site Master models test both waveguide and coaxial cables more conveniently than laboratory

17、-sized scalar analyzers or microwave test sets. Vector Error Correction Vector error correction within the S800 series improves the quality and convenience of measurements compared to traditional scalar techniques. Accuracy and repeatability account for errors such as test port match and source matc

18、h errors.Vector correction allows the test port to achieve the highest commercial directivity to 50 dB (frequency range dependent) using relatively small calibration components. Waveguide Dispersion Vector error correction also improves the quality of Distance- To-Fault data. Not only is the reflect

Unlike scalar-based systems, the Site Master S800 Series do not suffer reflec- tion magnitude errors (a failure looks better than actual) and length inaccuracies in proportion to the relative lengths of the coaxial input cable and waveguide under test.

41、ireless service covering the 2 MHz to 20 GHz frequency range, Site Master by Anritsu offers a cable and antenna analyzer solution for you. 1. On-Frequency Interference Immunity is specified to within 10 kHz of the carrier frequency. 2. On-Channel Interference Immunity is specified at 1 MHz of the ca

42、rrier frequency. 3. In most field applications, Immunity is typically better because interferring signals are modulated and varying in frequency rather than CW. Measurements were made in CW mode by injecting a signal into the Site Master through a coupler. 4. All Anritsu Site Master models include R

Built-in Auto-Averaging automatically reduces the effects of noise while zeroing control allows optimum measurement accuracy at low power levels. InstaCalCalibration Module* The InstaCa

45、l 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 u

46、sers 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 p

Microwave Accessories Calibration components mate directly to a variety of commercial and standard military flanges eliminating the necessity of bulky, precis

48、ion 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

49、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. InstaCalModule ICN50 *The InstaCalCalibration 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
