The NRX base unit can measure up to 4 channels with hardware and software options. It supports a range of sensor interfaces from the NRP and NRT series plus the NRQ6.  Sensors can be connected via 8-pole connectors (2 on front panel, with a further 2 as a hardware option NRK-B4 on the back panel), by USB (1 on the front panel, 1 on the back) or by Ethernet depending on the sensor requirements. It is also possible to use a single NRT sensor with the NRX-B9 hardware option on the front panel. 

A single channel of analysis is standard, with a second channel being enabled by software option NRX-K2 and channels 3 and 4 by option NRX-K4. 

The instrument supports all sensor-dependent measurement functions and, depending on the sensor, supports a frequency range from DC to 110GHz and power from 0.1fW to 30W.  Control is largely from the 12.7cm touchscreen with 800 x 480 resolution.
