The General Radio 1808 AC Millivoltmeter was only available in Catalog U (1970).
The Type 1808 is a solid-state, average-reading voltmeter calibrated to read the RMS value of sine waves. It has a frequency response from 10 Hz to 10 MHz, six ranges at 20 dB intervals, and a DC output that can be used to drive a recorder.
Specifications
- Range: 150 mVRMS to 150 VRMS in six 20-dB ranges
- Input Impedance: 10 MΩ at 1O pF except 12.5 MΩ on 15 V and 150 V ranges
- Accuracy: 1% basic accuracy
- Bandwidth: 10 Hz to 10 MHz
