VER TIC A L DEFLECTION SYSTEM
Deflection Factor
Channel 1 or 2 calibrated range
W ithout probe
1 mV to 10 V /div in 13 steps. Steps in a
1 -2-5 sequence.
With 10X probe
10 mV to 100 V /div in 13 steps. Steps in
a 1 -2-5 sequence.
Accuracy
Within 3% of indicated deflection.
Uncalibrated (VAR) range
Provides continuously variable deflection
factors between the calibrated steps.
Extends maximum uncalibrated deflection
factor to at least 25 volts/division.
Each deflection factor increased by a fac
tor of at least 2.5:1.
