R&S®SMIQ03HD Vector Signal Generator

High dynamic for WCDMA (3GPP)

This is a discontinued product
Please note the following successor product(s):

Wide dynamic range: ACLR 70 dB typ. for 3GPP test model 1, 64 DPCH

  • Single-carrier scenarios, enhanced features with option R&S SMIQB57 (3GPP downlink):
    Further improvement of ACLR (77 dB typ.)
    High output power (up to +30 dBm PEP)
  • High output power (up to +30 dBm PEP)
  • Multicarrier scenarios: integrated baseband filters to improve ACLR of 1 to 4 WCDMA carriers.
  • Short frequency and level setting time
  • Optional fading simulator (R&S SMIQB14/B15) and noise generator/distortion simulator (R&S SMIQB17)

Single carrier scenarios: Further ACLR performance boost (typical 77 dB) with option (R&S SMIQB57).

High ACLR Mode with R&S SMIQB57

The use of a special filter option (R&S SMIQB57) improves the signal quality of a WCDMA single-carrier signal in the downlink (2110 MHz to 2170 MHz) regarding adjacent-channel power to a level previously unattained by any signal generator (ACLR 77 dB in adjacent channel and 82 dB in alternate channel). The high output power of the option (up to +30 dBm PEP) is an additional benefit. Additional driver amplifiers for driving the components are not required. This is a great benefit especially for the manufacturers of base station components. Costs are reduced and signal quality is not impaired by the noise of an external amplifier. If more than one WCDMA carriers are to be generated, several R&S SMIQ03HD signal generators fitted with the R&S SMIQB57 option can be combined to provide a multicarrier scenario of highest spectral purity. Multicarrier scenarios can also be generated less elaborately using one signal generator only.

Single carrier scenarios: Further ACLR performance boost (typical 77 dB) with option (R&S SMIQB57).

ACLR measurement on single-carrier signal using R&S SMIQB57 (Low Distortion Output Mode)

Wide dynamic range for single-carrier and multicarrier signals through integrated baseband filters for highest ACLR at 1 to 4 WCDMA carriers

ACLR on four-carrier signal

Multicarrier signals can be generated by the R&S SMIQ03HD with optionally integrated Arbitrary Waveform Generator R&SSMIQB60, or by the R&S SMIQ03HD in combination with the I/Q Modulation Generator R&S AMIQ. The WCDMA multicarrier signals are calculated with the aid of the user-configurable R&S WinIQSIM Software that is available free of charge, and transferred to the arbitrary waveform generators. For each of the four scenarios (1 to 4 carriers), an I/Q filter (integrated as standard) with a cutoff frequency of 2.5 MHz, 5 MHz, 7.5 MHz or 10 MHz is switched on. Optimum ACLR values are thus obtained for each of the four possible carrier scenarios.

Multi carrier scenarios: Integrated I/Q filters to improve ACLR for up to 4 WCDMA carriers

Four I/Q filters with different bandwidths allow to increase the ACLR performance of one- to four-carrier WCDMA signals.

Short setting time for level and frequency

For cost-effective production, a high throughput of modules or devices is required. With its extremely short setting times (frequency/level setting time: <3 ms/<2.5 ms) the R&S SMIQ03HD easily meets this requirement. Setting times can be further reduced in special modes (List mode: <500 µs, Fast Restore mode: <800 µs).

Optional fading simulator or noise generator/distortion simulator

For universal applications of the R&S SMIQ03HD, fading simulators (R&S SMIQB14/B15) and a noise generator/ distortion simulator (R&S SMIQB17) can be used to generate realistic signals. The Vector Signal Generators R&S SMIQ are the only generators on the market that can be equipped with internal fading simulators (one-box solution). Moreover, it is possible to use an additional option (R&S SMIQB49) for generating 3G fading scenarios (dynamic fading, 3GPP TS 25.141) for performance tests.
