The NRQ6 is based on receiver technology and can perform band-limited power measurements down to -130 dBm. The NRQ6 combines high-precision with high-speed measurements beyond the limits of currently available power meters. In addition to conventional continuous average measurements, the NRQ6 has a trace display function and also performs ACLR measurements. The optional NRQ6-K1 I/Q data interface, NRQ6-K2 power servoing and NRQ6-K3 phase coherent measurements options complete the NRQ6 as new category of test and measurement devices.

|
| I/Q Data Capturing | 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.
|
| Fast Power Servoing with SGT100A | 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.
|
| Phase Coherent Measurements | 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
|
| High Measurement Speed | 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.
