The Rohde & Schwarz, Inc. SML02 signal generator is an
electronic instrument that generates repeating electronic signals. It
contains an electronic oscillator, a circuit that is capable of
creating a repetitive waveform.
The R&S SML Series combines all
the characteristics of a general purpose signal generator - wide frequency ranges, extensive analog modulation capabilities and high reliability - into a lightweight, low-cost product.Thanks to its low phase noise SML is ideally suited to replace Los, and with precise DC-coupled FM modulation the SML can be used as an accurate VCO.
The SML in conjunction with the optional Pulse Modulator SML-B3 handles all analog types of modulation. AM, FM/phase and pulse modulation can be
used simultaneously. TDMA signals or amplitude variations at FM, for example, can thus be simulated. The SML has plenty of power in reserve so level loss produced by the test setup can be easily compensated. Its high output level makes SML an ideal source for driving high-level mixers. Production test systems, in which the signal is taken to the DUT via switches and cables, cause level losses which can be easily compensated by the high output power of SML.Sensitivity measurements
require a signal generator with high level accuracy. This is particularly true at low output levels. With its sophisticated calibration technique, SML features high level accuracy.
Squelch measurements call for continuous level setting. Non-interrupting level variation by typically 30 dB makes SML the ideal choice for squelch measurements. Protection against overvoltage - The integrated overvoltage protection of SML protects against very high external voltages as they may occur during
transceiver measurements.The SML Series provides high accuracy and fast
settling. In production testing, compliance with specified tolerances
is checked. The tolerance range is further limited by the inaccuracy of
the measuring equipment used. Thanks to its high level accuracy of
<0.5 dB (at levels >-120 dBm) SML reduces the accuracy requirements made on the DUT. This results in higher yield. Speed is of prime importance in production. And this is exactly one of the strong points of SML, with a setting time <10 ms for frequency and level.Simultaneous modulation - TDMA signals can be simulated since SML offers simultaneous AM, FM/phase and pulse modulation. SML is suitable, for example, for measurements in line with standards ENV 50204 (test of
immunity to high-frequency electro-magnetic fields of digital radio
telephones) and MIL-STD-462D (measurement of electromagnetic
interference characteristics).
