The NRQ6 can be used as a standalone RF front end to capture vector-modulated I/Q signals.

With the optional NRQ6-K1 I/Q data interface, captured I/Q data can be read out using SCPI commands.

The data is demodulated and analyzed using external software, e.g. VSE.

With the NRQ6 version 2.10 and the VSE version 1.70, direct data aquisition and control is possible.

In component test applications non-linear characteristics of DUT's make it difficult to set up a specific output power.

The NRQ6-K2 power servoing option enables a dedicated serial communications channel over the trigger connectors between NRQ6 and SGT100A.

The desired power will be set in several iterations and is finished typically in 1 ms to 1.5 ms.

The synchronous phase coherent measurements (option NRQ6-K3) are based on a primary/secondary relationship between two or more NRQ6.

The primary forwards the local oscillator signal (LO) and its clock signal (CLK) to the secondary(ies) and triggers and secondary(ies).

The RF phases can be measured at up to 8 ports, where the typical uncertainty is only 0.1 degree at an power of -60 dBm

Every diode based power meter works without band limitation in the specified frequency range. Precise measurement of low-power signals requires averaging of multiple measurement samples and this increases the measurement time.

The diode based power meter technology is mature, and therefore only limited product innovations are possible.

The receiver technology based NRQ6 has significantly increased the measurement speed for low-power signals.
