Frequency Response ? dBm
Input
0 dBm = 5 Hz to 380 kHz
10 dBm = 5 Hz to 370 kHz
20 dBm = 5 Hz to 240 kHz
30 dBm = 5 Hz to 100 kHz
40 dBm = 5 Hz to 45 kHz
50 dBm = 5 Hz to 17 kHz
Calibration
First, calibrate the 0 dB reference level by applying a 1 kHz sine
wave from an audio oscillator at the desired 0 dB amplitude.
This can be anywhere from 0 dBm (770 mV rms 2.2 V p-p)
to 20 dBm (77 mV rms 220 mV p-p). Adjust the IREF
calibration trimmer for a zero indication on the analog meter.
Then, calibrate the meter scale factor or gain. Apply an input
signal 40 dB below the set 0 dB reference and adjust the scale
factor calibration trimmer for a 40 糀 reading on the analog meter.
The temperature compensation resistors for this circuit can be
purchased from Micro-Ohm Corporation, 1088 Hamilton Rd.,
Duarte, CA 91010, Part #Type 401F, 2 k?,1% + 3500 ppm/癈.
