Product Description
The Tektronix TSG4100A Series brings you mid-range performance and up to 200 MHz modulation bandwidth for the price of an entry-level RF signal generator.
They offer exceptionally high frequency resolution (1 μHz at any frequency) and use a new technique that provides outputs with low phase noise (-113 dBc/Hz at 20 kHz offset from 1 GHz carrier).
Analogue modulation is featured as standard, with convenient, in-field software upgrades allowing for easy transition to more advanced vector and digital modulation capabilities.
The Tektronix TSG4100A Series complements other leading Tektronix mid-range RF test equipment, such as the USB-based RSA306 Spectrum Analyzer and MDO4000B and MDO3000 Mixed Domain Oscilloscopes.
An ovenised SC-cut oscillator (TSG410xA-M00 or E1 models) time-base provides a 100x improvement in stability (and a 100x reduction in the in-close phase noise) compared to instruments that use a TCXO time-base.
Other key features include Dual baseband ARB generators; Digital modulation applications for GSM, EDGE, W-CDMA, APCO-25, DECT, NADC, PDC, and TETRA
USB, GPIB, RS-232, and LAN interfaces; just 12 pounds (5.6 kg) weight and rack dimensions of 2U high and half standard width.
Analogue modulation
Modes include amplitude modulation (AM), frequency modulation (FM), phase modulation (ΦM), and pulse modulation. The internal modulation source produces sine, ramp, saw, square, and noise waveforms. An external modulation signal may also be applied to the rear panel modulation input.
Vector modulation
Full support is available for vector signal modulation on RF carriers between 400 MHz and 6.0 GHz. It features a dual arbitrary waveform generator operating at 125 MHz for baseband signal generation, supporting most common vector modulation schemes: ASK, QPSK, DQPSK, π/4 DQPSK,
8PSK, FSK, CPM, QAM (4 to 256), 8VSB, and 16VSB. It also includes built-in support for all the standard pulse shaping filters used in digital communications.
External I/Q modulation
The rear-panel BNC I/Q modulation inputs and outputs enable arbitrary vector modulation via an external source, supporting up to 400 MHz of RF bandwidth with a full scale range of ±0.5 V and a 50 Ω input impedance.
