Tektronix has introduced the TSG4100A series which are a series of vector signal generators at an affordable price. This new series complement other leading mid-range RF test solutions from Tektronix, such as the USB-based RSA306 spectrum analyzer, MDO4000B and MDO3000 mixed domain oscilloscopes. As the needs of an engineer change, the TSG4100A can be easily upgraded in the field to deliver more advanced vector and digital modulation capabilities. The TSG4100A is the first vector RF signal generator from a tier-one vendor with a price point of less than $15,000.
Key Features of the TSG4100A VSG Series:
Great RF Performance: The TSG4100A series includes three models with carrier frequencies from DC to 2 GHz, 4 GHz and 6 GHz. The instruments provide spur-free outputs with low phase noise (–113 dBc/Hz at 1 GHz), outstanding amplitude accuracy (<+/- 0.4 dB at 1 GHz, 0dBm CW signal from +16dBm to -100 dBm level range) and excellent frequency resolution (1 μHz at any frequency). An oven-controlled crystal oscillator time-base provides <±0.002 ppm temperature stability and <±0.05 ppm aging stability, the most accurate and stable available for a mid-range signal generator.
Analog Modulation: The TSG4100A signal generators offer a wide variety of modulation capabilities. Modes include amplitude modulation (AM), frequency modulation (FM), phase modulation (ΦM), and pulse modulation. There is an internal modulation source as well as an external modulation input. Unlike most analog signal generators, the TSG4100A can sweep continuously from DC to 62.5 MHz. And for frequencies above 62.5 MHz, each sweep range covers more than an octave.
Vector Modulation: Units can be software upgraded to support VSG applications. With the vector upgrade, TSG4100A series offers full support 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. The generator has built-in support for the most common vector modulation schemes: ASK, QPSK, DQPSK, π/4 DQPSK, 8PSK, FSK, CPM, QAM (4 to 256), 8VSB, and 16VSB. It also includes the standard pulse shaping filters used in digital.
