Rohde & Schwarz SML03 Signal Generator w/ High Spectral Purity 9 kHz – 3.3 GHz

Rohde & Schwarz SML03 Signal Generator w/ High Spectral Purity 9 kHz – 3.3 GHz

Description

High spectral purity

Owing to its low phase noise, the Rohde & Schwarz SML03 Signal Generator w/ High Spectral Purity 9 kHz – 3.3 GHz is ideally suited to replace LOs.

Versatile modulation modes
The Rohde & Schwarz SML03 Signal Generator w/ High Spectral Purity 9 kHz – 3.3 GHz in conjunction with the optional Pulse Modulator ¸Rohde & Schwarz SML03 Signal Generator w/ High Spectral Purity 9 kHz – 3.3 GHz handles all analog types of modulation. AM, FM/ϕM and pulse modulation can be used simultaneously. TDMA signals or amplitude variations in the case of FM, for example, can thus be simulated.

High and precise output level
The Rohde & Schwarz SML03 Signal Generator w/ High Spectral Purity 9 kHz – 3.3 GHz has plenty of power in reserve so level loss produced by the test setup can be easily compensated. Its high output level makes the Rohde & Schwarz SML03 Signal Generator w/ High Spectral Purity 9 kHz – 3.3 GHz an ideal source for driving high-level mixers.

Excellent modulation characteristics
The DC-coupled FM allows the ¸SML to be used as an accurate VCO.
Example: receiver measurements

◆ Sensitivity measurements require a signal generator with high level accuracy. This is particularly true at low output levels. With its sophisticated calibration technique, the Rohde & Schwarz SML03 Signal Generator w/ High Spectral Purity 9 kHz – 3.3 GHz features high level accuracy (<0.5 dB at levels >−120 dBm).
◆ Squelch measurements call for continuous level setting. Non-interrupting level variation by typ. 30 dB makes the Rohde & Schwarz SML03 Signal Generator w/ High Spectral Purity 9 kHz – 3.3 GHz the ideal choice for squelch measurements.
◆ Low spurious, low broadband noise and above all excellent SSB phase noise are prerequisites for using a signal generator as an interference
source. With typ. −128 dBc (1 Hz) SSB phase noise (at f = 1 GHz, Δf = 20 kHz), spurious suppression of typ. −76 dBc and broadband noise of
typ. −150 dBc (1 Hz), the ¸SML easily meets even the most exacting requirements.
