Uncertainties
Represent limits of measurement uncertainty for a given measurand. Uncertainty is defined with a coverage factor of 2 and has been
calculated in line with the rules of the Guide to the Expression of Uncertainty in Measurement (GUM), taking into account
environmental conditions, aging, wear and tear.
Device settings and GUI parameters are indicated as follows: “parameter: value”.
Non-traceable specifications with limits, typical data as well as nominal and measured values are not warranted by Rohde & Schwarz.
In line with the 3GPP/3GPP2 standard, chip rates are specified in million chips per second (Mcps), whereas bit rates and symbol rates
are specified in billion bits per second (Gbps), million bits per second (Mbps), thousand bits per second (kbps), million symbols per
second (Msps) or thousand symbols per second (ksps), and sample rates are specified in million samples per second (Msample/s).
Gbps, Mcps, Mbps, Msps, kbps, ksps and Msample/s are not SI units.
Introduction
The R&S®CMX500 radio communication tester is a universal network emulation and measurement test solution supporting latest
3GPP 5G NR technology. In combination with the R&S®CMW500, it supports both 3GPP 5G NR standalone (SA) and non-standalone
(NSA) mode with LTE anchor cell and integrated end-to-end data testing within an integrated solution.
Testing within the 3GPP FR2 frequency range can be conducted by combining the R&S®CMX500 with the R&S®CMXHEAD30 remote
radio head (RRH), which is a separate compact unit that performs upconversion and downconversion from IF to 5G NR FR2 frequency
ranges.
The split concept with the R&S®CMX500 and the R&S®CMXHEAD30 allows short RF cable lengths at the 5G NR FR2 frequency
range for an optimal link budget in radiated chamber test environments like the R&S ®CMQ500 shielding cube or the R&S®ATS800R
CATR rack based antenna test system.
Vector signal analysis and ARB generator are built-in capabilities of the R&S®CMX500 that allow efficient RF parametric testing of
both FR2 transmitters and FR2 receivers.
Receiver tests of 5G NR devices under 3GPP fading propagation conditions can be performed using the internal baseband fading
emulation.
The R&S®CMX500 can be used in all product development and lifecycle phases – from early R&D to service.
