Midrange vector signal generator with mmWave testing capabilities

The R&S®SMM100A vector signal generator provides remarkably good RF characteristics across the entire frequency range from 100 kHz to 44 GHz. The instrument covers the bands up to 7.125 GHz used by the wireless standards for 5G NR FR1 and Wi-Fi 7 as well as the 5G NR FR2 bands up to 44 GHz.
The internal baseband generator in the R&S®SMM100A supports a maximum RF modulation bandwidth of 1 GHz. Digitally modulated broadband signals can thus be generated as required by the prevalent wireless standards. The R&S®SMM100A is well prepared for future bandwidth requirements.

Features & benefits

Excellent SSB phase noise and EVM performance

SSB phase noise of < –129 dBc is specified for an RF frequency of 1 GHz with a 20 kHz offset for the R&S®SMM100A vector signal generator. The typical value of –134 dBc is even 5 dB lower. The R&S®SMM-B709 low phase noise option lowers SSB phase noise to –139 dBc. In addition to excellent RF performance, it also has outstanding modulation characteristics at higher frequencies. The R&S®SMM100A delivers impressive EVM performance of < –45 dB  at an RF frequency of  28 GHz for a 400 MHz 5G NR signal.

Improved performance at higher output power

Activating the R&S®SMM-K575 RF linearization option significantly improves the EVM performance at higher output power. EVM performance improves by 8 dB for 100 MHz 5G NR signals in line with 3GPP TM 3.1 at 3.4 GHz and output power of 10 dBm. The same is valid for ACLR performance in the adjacent channel.

Discover scalability

The basic configuration of the R&S®SMM100A supports a maximum RF modulation bandwidth of 120 MHz. Depending on requirements, bandwidth can be extended up to 1 GHz with a license key. With similar flexibility, the ARB memory can be extended from 64 Msample up to a maximum of 2 Gsample. 
  The R&S®SMM100A also comes with various frequency options up to a maximum of 44 GHz. Users can precisely configure the R&S®SMM100A to meet actual requirements.

Mobile communications standards

The R&S®SMM100A is well suited for generating signals that comply with the most important wireless communications standards and is an ideal signal generator for 5G NR base station conformance testing.
  The R&S®SMM-B1044 frequency option can cover 5G NR frequency ranges FR1 and FR3 up to 24.25 GHz and FR2 up to 44 GHz. The bandwidth extension to 1 GHz can handle increased signal bandwidth 5G requirements.

The 5G NR test case wizard allows the R&S®SMM100A to be conveniently and cleverly configured for BTS tests in line with 3GPP TS 38.141.

Ready for Wi-Fi testing

The preceding WLAN standards IEEE 802.11ac and IEEE 802.11ax use a maximum signal bandwidth of 160 MHz. However, the trend for WLAN is toward larger bandwidths and higher frequencies. IEEE 802.11be (Wi-Fi 7) specifies a signal bandwidth of 320 MHz in the frequency range from 5.8 GHz to 7.125 GHz. The R&S®SMM100A satisfies the signal quality requirements with an EVM of better than –53 dB for a signal bandwidth of 320 MHz.

High rate pulse (HRP) ultrawideband (UWB)

The R&S®SMM100A is ideal for HRP UWB receiver testing. The instrument covers the frequency range up to 10.6 GHz and with an RF modulation bandwidth of 500 MHz, signals can be generated on the most important channels.
  The R&S®SMM-K149 HRP UWB baseband option supports signal generation for three specified modes: HRP UWB from IEEE 802.15.4 as well as the BPRF mode and the HPRF mode for enhanced ranging devices (ERDEF) from IEEE 802.15.4z.
