Input impedance
Maximum input voltage
VERTICAL DEFLECTION SYSTEM (2 identical channels)
Bandwidth and rise time
DC to at least 35 MHz and rise time 1 0 ns or less DC to
at least 7 MHz and rise time 50 ns or less at magnifier
extends. The AC c oupled lower - 3 dB point is 1 0 Hz or
less.
Deflection factor
5 mV/div to 5V/div in IO calibrated steps in a 1 -2-5
sequence . Uncalibrated continuous control extends de ­
flection factor to at least 1 2 .5 Volts per division in the
5 Volts/div position. x5 magnifier increases sensitivity of
each deflection factor setting to l mV/div.
Accuracy
±3 %
Additional error for magnifier ±2%.
Display modes
CH l , CH2 (normal or invert), Alternate , Chopped
(approximate 2 5 0kHz), Added
33 kohm (typ.)
30 V(DC +peak AC)
Input impedance
Approximately 1 Mil in parallel with 25 p F
Maximum input voltage
300V (DC + peak AC) or 5 00 Vp- p AC at I kHz or less
Input coupling
AC , GND , DC
HORIZONTAL DEFLECTION SYSTEM
Time base
0.2µs/div to 0.2s/div in 1 9 calibrated steps in a 1 -2-5
sequence . Uncalibrated continuous control extends de­
flection factor to at least 0.5 seconds per division in
the 0 .2 sec/div position. x l O mag extends maximum
sweep rate to 20 ns/div.
Accuracy
±3 %
Additional error for magnifier ±2%
