The LMV-181A is an average responding rms reading ac millivoltmeter and applicable to a wide range of general purpose measurements. The model feature a high sensitivity of 100 m V and ranges to 300 V rms maximum full scale with a wide bandwidth of 5 Hz to 1 MHz. Meter scales are conveniently calibrated in millivolts and dB (0 dBV = 1 V and 0 dBm = 0.775 V) with accuracy's to within ± 2% f.s.
For audio, the LMV-181A is apt for measuring record and playback levels, channel separation. balance and tracking tests of volume, loudness and tone controls versus frequency, etc.
The flat bandwidth of the amplifier output terminals permit it to be used as sensitive, accurate instrument preamplifier. Other areas of use include test and repair for communications. IF and ultrasonic circuits and systems. |
