Section 1—7A18A
SPECIFICATION
The following electrical characteristics are valid over the
stated environmental range for instruments calibrated at an
ambient temperature of +20°C to +30°C, andafter a five
minute warmup unless otherwise noted.
The 7A18Ais a dual-channel, medium-bandwidth amplifi-
er. Internal gain and compensation circuits are automatically
switched to correspond to the setting of the VOLTS/DIV

Characteristic Performance Requirement Supplemental Information
Deflection Factor
Calibrated Range 5 mV/Div to 5 V/Div; ten steps in a
1,2,5 sequence.
Deflection Factor Accuracy Within 2%with GAIN adjusted at
10 mV/Div.
Uncalibrated (VARIABLE) Continuously variable between
calibrated steps; extends deflection
factor to at least 12.5 V/Div.
GAIN Permits adjustmentof deflection factor for
calibrated operation with all 7000-series
oscilloscopes.
