878xx Signal Generators

The Keysight 878xx Series of Vector Signal Generators is ideal for assessing modern advanced telemetry and terrestrial and satellite communications receivers. Multiple advanced modulators are contained in one of these programmable signal generators, eradicating the necessity of purchasing multiple types of test equipment. Automatic calibration is easily accessible with a single button. These Vector Signal Generators can perform the following measurements: digital modulation, AM, I/Q, FM, and phase modulation. The Keysight 878xx Series can also simulate numerous modulations at the same time, which provides these signal generators with further flexibility.

Since the Vector Signal Generators in the Keysight 878xx Series run at a set frequency, the model’s I/Q modulator delivers extremely precise modulation with minimal quadrature mistakes and amplitude imbalance. The outcome of this process is calibrated I/Q modulation over higher than 8 octaves of range. This would not be plausible with a customized modulator because they utilize direct modulation methods. The 8780A Vector Signal Generator supports 8PSK, 64QAM, 16QAM, BPSK, and QPSK (with Option 64) with symbol rates as high as 150 MHz, encompassing the majority of terrestrial and satellite communications applications. One of the most difficult applications for an FM modulator is the creation of video signals. However, the signal generator’s AC FM is created to perform well for this type of application.
