the associated VOLTS/DIV readout. The ground symbol is also
displayed after the value readout of any of the VOLTMETER
measurements.
A C —Capacitively couples the input signal to the vertical attenuator
when the AC button is lit.
Turning on AC Coupling turns off DC Coupling. AC Coupling blocks the
dc component of the input s ig n a l The lower -3 dB frequency limit is
10 Hz or less when using either a IX probe or property terminated
coaxial cable; it is 1 Hz or less using a compensated lOXprobe.W ithAC
Coupling selected, an AC symbol (~ ) is displayed to the right of the
associated VOLTS/DiV readout. An AC symbol is aiso displayed after
the value readout of any Peak or Peak-to-Peak voltage measurement.
NOTE
When AC Coupling is selected for DC voltmeter measure
ments an error message “SELECT DC COUPLING" is
displayed.
DC—Couples dc and ail frequency components of the input signal to
the vertical attenuator when the DC button is lit.
Turning on DC coupling turns off AC coupling. With DC Coupling
selected, a DC symbol ( nrs ) is displayed to the right of the associated
VOLTS/DIV readout. Input resistance is 1 M fl to ground.

CH 1 OR X and CH 2 In p u t C o n n e c to rs —Connect signals to the In
puts of Channel 1 and Channel 2 vertical attenuators.
Input connectors are BNC type with an outer contact ring for recog
nizing attenuation factors of coded attenuator probes. A signal con
nected to the CH 1 OR X input connector produces the horizontal
deflection (X-Axis) in the X -Y horizontal mode. Any of the vertical signal
channelsorADDcan provide vertical deflection (Y-Axis) for an X-Y dis
play.
1^9) PROBE ADJUST C onnector — Outputs a 0.5 V square-wave signal (at
about 1 kHz into a 1 MO load) for compensating voltage probes and
checking the vertical deflection accuracy.
