Agilent / HP 312A
Frequency Selective Voltmeter
Description
This unit is easy to operate and capable of making transmission and noise measurements with unparalleled speed and accuracy.
Some of the other features include built-in AFC circuitry, internal CAL output (1MHz) and digital frequency readout.
Key Points
Frequency range from 1KHz to 18MHz in 18 bands (±10Hz accuracy).
Three adjustable bandwidths: 200Hz, 100Hz, and 3100Hz.
Sensitivity: -97dBm to +23dBm (50 to 150-ohms); -107dBm to +13dBm (600ohms).
Receiver mode outputs: AM, AM/AFC, LSB, USB.
Full scale voltage ranges from 3µV to 3V (50ohm reference).
Built-in AFC circuitry.
Internal CAL output (1MHz).
