Tektronix TSG4106A RF Signal / Vector Generator Review, Teardown & Experiments

In this episode Shahriar presents a detailed review of the new Tektronix TSG4106A RF Signal / Vector Generator. The key features are:

  • True DC to 2 GHz, 4 GHz or 6 GHz to support both analog and vector/digital signal generation.
  • Typical ≤±0.30 dB amplitude accuracy (0 dBm CW signal at 22 ºC) from 10 MHz to 6 GHz.
  • I/Q modulation inputs (400 MHz RF bandwidth).
  • ASK, FSK, MSK, PSK, QAM, VSB, and custom I/Q.

A complete teardown of the unit is presented along with an explanation of various functions, components and sub-systems. The basic unit performance is verified using a Keysight EXA Signal Analyzer. The TSG4106A is then used to along with an Analog Devices I/Q de-modulator whose output is examined for performance verification.
