ELECTRICAL SPECIFICATIONS
INPUT RESISTANCE:
SIGNAL DETECTION:
DETECTION ACCURACY: ± 1 dB maximum error, sine wave input.
MAXIMUM SENSITIVITY: 100 μV rms of sine wave corresponds to bottom scale on most sensitive range.
GAIN STABILITY: Temperature: Less than 2 dB/10°C, 0°to 40°C. Line Voltage: Less than 0.5 dB, 103 to 127 volts.
ATTENUATION: 50 dB span ranges: 9 bottom scale ranges at
100 μV, 320 μV, 1 mV, 3.2 mV, 10 mV, 32 mV, 100 mV, 320 mV and 1 volt. Top scale is nominally 50 dB (320X) above bottom scale.
100 dB span ranges: 4 bottom scale ranges at
ATTENUATION ACCURACY: ± 3% maximum error (0.25 dB) for
OUTPUT:
OUTPUT RESISTANCE: Approximately 10 ohms.
SIGNAL BANDWIDTH: 5 Hz to 100 kHz, less than 3 dB down from
SIGNAL CREST FACTOR: 3 to 1 at full scale on 100 dB span, ±500 volts peak maximum allowed.
DETECTION RESPONSE TIME: For a step change in input amplitude with ratio of 40 dB (100:1) or greater, the time required for the output to increase or decrease between values corresponding to 105 and 90% of the maximum applied signal (i.e. , 20 dB below max. applied signal and 1 dB below max applied signal) is approximately 20 msec in FAST position and 2 sec in SLOW position. i. e. , average rate of change of output under these conditions corresponds to approximately 900 dB/ sec in FAST: 9 dB/sec in SLOW.
OUTPUT NOISE: Maximum noise appears at bottom scale. 50 dB span: 80 mV pp: 100 dB span: 40 mV pp.
INTERNAL CALIBRATION:
GENERAL SPECIFICATIONS
Terminals: DC output on front panel. Input and auxiliary DC output on rear of mating power supply.
Front Panel Controls: RANGE switch; GAIN potentiometer locking; LOG ZERO,
Internal Controls: Signal Board: Balance adjust; CAL adjust (2); Zero Suppression adjust; Attenuator compensation
trimmers (4). Detector Board: 100 dB span
Weight: Approximately 5 lb. (2, 3 kg).
Front Panel Dimensions: 7" high,
Note: When Preamplifier is used in a recording system, these specifications are affected by performance of the recorder and driver amplifiers. (Consult data sheet of appropriate system for details.)
All Sanborn 8800 Series Amplifiers are tested for performance under normal production environmental conditions: ambient temperature 20°to 30°C and relative humidity less than 80% unless otherwise noted.
