Field engineers often need multiple instruments to perform antenna installation and maintenance tasks: a cable and antenna analyzer, a spectrum analyzer, a signal generator and a bias source. The two port R&S Cable Rider ZPH combines all of these instruments with additional features.
The two-port architecture provides S21 transmission measurements, spectrum analysis and tracking generator functionality. The handheld instrument features high sensitivity with a displayed average noise level (DANL) typically better than –146 dBm up to 3 GHz as a spectrum analyser for RF diagnostics in the field. The optional R&S ZPH-B22 preamplifier improves sensitivity even further, to a DANL of typically –163 dBm. This is especially useful during interference analysis as it enables the detection of weak signals.
The new tracking generator functionality makes scalar transmission measurements possible, e.g. frequency response measurements on RF filters. The internal bias source adds further functionality, such as for performing measurements on tower mounted amplifiers (TMA). In addition, the Cable Rider ZPH can use its unique independent signal source to operate as a continuous wave (CW) signal generator.
Like previous models, the R&S Cable Rider ZPH offers measurement speed of 0.3 ms per point and fast boot and warm-up. There is also no need to calibrate the analyser before use, saving time on site.
The instrument's wizard function simplifies and speeds up measurements so that field technicians only need to execute the test sequences as shown on the display. The wizard guides them through measurements in easy-to-follow steps. This reduces test time during installation and maintenance.
The R&S Cable Rider ZPH weighs 2.5kg and has a battery life of up to nine hours. It also has a large colour touchscreen with intuitive operation via smartphone-like gestures and has extra-large keys that allow easy handling even when the user wears heavy-duty work gloves.
The base unit covers a frequency range of up to 3 GHz. Extending the frequency range to 4 GHz is straightforward with the R&S ZPH-B4 option, which is enabled via
