The Rohde & Schwarz SMHU58 Signal Generator can generate complex test signals for modern communications and radar systems. Its high versatility is based upon the great variety of modulation capabilities in conjunction with high spectral purity and frequency hopping.

The I/Q and the broadband AM/FM modulators make all digital and analog modulation modes for directional radio and satellite communications possible. Modern radio networks use digital modulation methods, for which the SMHU58 is ideally suited due to the high accuracy of its I/Q modulator.

For modulation using serial data signals, coders can be integrated for the necessary signal processing and filtering to relevant standards. The optional coders produce filtered analog signals from a serial data stream for driving the I/Q modulator. The accuracy of the resulting phase modulation meets all requirements placed on a reference signal for NADC, DECT, PDC, and GSM testing. The CDMA coder uses Qualcomm chips to generate standard channels.

Broadband FM can be used for fast FSK, analog sweeping, video modulation, and for generating chirp signals.
