Keysight (Agilent) 8780A 3 GHz Vector Signal Generator

The HP 8780A Vector Signal Generator is a synthesized IF source with exceptional modulation for modern receiver and component testing. It has built-in DACs (digital-to-analog-converters) to simplify generation of common digital modulations. Its extra-wide modulation bandwidth comes from a vector modulator that effectively doubles baseband modulation bandwidths for 700 MHz of output modulation. The vector signal generator's wideband modulation is complemented with an unmodulated coherent carrier output for demodulation of test signals. The 8780A Vector Signal Generator offers a wide variety of modulation using both digital and analog inputs. It generates many standard digital modulations like QPSK and 16QAM and traditional modulations like FM, AM and pulse. By combining the different modulation types, signals as diverse as Barker-coded radar pulses and dopplershifted satellite signals can be simulated. Specifications. Frequency Range: 10 MHz to 3 GHz. Resolution: 1 Hz. Output Level range: + 10 to -100 dBm < 2.5 GHz, +4 to -100 dBm >= 2. 5 GHz, (+ 12 dBm <= 3 GHz with Opt 064). Modulation types: BPSK, QPSK, 8PSK, 16QAM (64QAM with Opt. 064), Arbitrary 2-State, Burst (except 64 QAM). Opt 001: Rear panel output and modulation inputs. Opt 002: + 10 dBm Coherent Carrier output. Opt 064: 64 QAM modulation. Opt H02: Analog Phase Modulation.

dBc
dBc (decibels relative to the carrier) is the power ratio of a signal to a carrier signal, expressed in decibels. If the dBc figure is positive, then the relative signal strength is greater than the carrier signal strength. If the dBc figure is negative, then the relative signal strength is less than carrier signal strength.

Load Regulation
Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply's load (such as a change in resistance value connected across the supply output).

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Settling Time
Settling time of an output device is the time elapsed from the application of an ideal instantaneous step input to the time at which the amplifier output has entered and remained within a specified error band, usually symmetrical about the final value.
