1 Welcome to the R&S SMM100A

The R&S SMM100A is a new signal generator developed to meet demanding customer

requirements. Offering excellent signal characteristic and straightforward and intuitive

operation, the signal generator makes signal generation fast and easy.

1.1 Key features

Outstanding key features of the R&S SMM100A are:

●Frequency range from 100 kHz to 44 GHz

●Up to 1 GHz I/Q modulation bandwidth (in RF) with internal baseband

●Support of important digital standards such as 5G NR, LTE incl. eMTC/NB-IoT,

HRP-UWB 802.15.4, WLAN IEEE 802.11a/b/g/n/ac/ax/be, LoRa

●Excellent signal quality for high accuracy in spectral and modulation measure-

ments

●Intuitive operation via touchscreen with block diagram as key element

●Graphical signal monitoring at practically every point in the signal flow

●SCPI macro recorder and code generator for generating executable remote control

code from manual operating steps (for MATLAB®, CVI, etc.)

For more information, see data sheet.

1.2 What's new

This manual describes firmware version FW 5.20.043.xx and later of the

R&S®SMM100A.

Compared to the previous version, it provides the new features listed below:

●Telemetry SOQPSK-TG modulation and related settings added for custom digital

modulation, see "Set according to Standard" on page 116 and Table 4-6.

●Checking parameter and settings dependencies, see Chapter 11.3, "Checking

parameters and dependencies", on page 550.

●HUMS settings: SNMP communication extended by version SNMPv3 that also sup-

ports SNMP user-defined profiles, see Chapter 12.5.8, "HUMS enhanced settings",

on page 628.

●NRP closed loop power control to achieve a constant input power at the DUT in

real time, see Chapter 7.12.4.3, "NRP power control", on page 406.

●Delayed internal adjustment settings to start the internal adjustments at a specified

time and automatic shut-down of the instrument when completed, see Chap-

ter 16.3.3.2, "Delayed adjustment settings", on page 1062.
