Rohde & Schwarz adds two-port model to its R&S Cable Rider ZPH
Rohde & Schwarz has expanded its handheld Cable Rider ZPH cable and antenna analyzer portfolio with a two-port model that supports network infrastructure manufacturers and network operators even more efficiently in installing and maintaining the growing number of mobile communications antenna systems.
The new R&S Cable Rider ZPH model now provides transmission measurements (S21) and offers spectrum analyzer and tracking generator functionality. With high sensitivity with a displayed average noise level (DANL) typically better than –146 dBm up to 3 GHz, the R&S Cable Rider ZPH is a powerful spectrum analyzer 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 R&S 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 a measurement speed of 0.3 ms per point and the fastest boot and warm-up time on the market. Moreover, there is no need to calibrate the analyzer before use, saving time on site.
Being hand-held and battery powered, the R&S Cable Rider ZPH is ideal for use in the field. It weighs just 2.5 kilograms, and can handle a full 9 hour's work without interruption. The analyzer also has a large colour touchscreen for intuitive operation with smartphone-like gestures, plus extra-large keys that allow easy handling even when the user wears heavy-duty work gloves.
The R&S Cable Rider ZPH 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 a keycode.
