Potomac Instrument AG-51 Audio Generator
Price:

Location:
Oklahoma City, OK
Description:
This unit is used , but has been taken care of and works just great, comes with the manual The AG-51 Audio Generator contains a low distortion 20 Hz to 200 kHz sine wave generator, an SMPTE standard intermodulation signal generator and a fixed frequency sine wave generator at 3.15 kHz for wow and flutter tests. Signal outputs are simultaneously available at levels of up to +20 dBm (equivalent sine wave power for complex signals) at separate left (L OUT) and right (R OUT) output connectors. Outputs may be selected for left (L) only, right (R) only, left and right in phase (L+R), and left and right in phase opposition (L-R). Fully balanced or unbalanced outputs at impedance levels 150 ohms or 600 ohms are front panel selectable. Three precision attenuators (10, 1.0 and 0.1 dB) provide a dynamic range of 99.9 dB in 0.1 dB steps. Attenuator dials display the output level directly in dBm in the 150 ohm source impedance configuration. Automatic output leveling circuitry with a built-in self-test feature provides a constant output level thereby eliminating the need for output metering. In the TEST mode the generator output level is reduced to zero, a useful feature during noise measurements. The time constant of the leveling control loop is determined by a front panel switch. For rapid frequency response measurements, this switch is set to the FAST RESPONSE position. This feature enables the operator to evaluate frequency response of the device under test (amplifier, filter, etc.) with a manual sweep of the frequency dial and multiplier switch. For distortion measurements, the switch is set to the LOW DIST position. This mode of operation provides minimum distortion with a slightly longer control loop time constant for accurate signal analysis at any specific frequency.
