5 V, 50 V
The 5 V range is for input signals that do
not exceed 5 volts peak-to-peak amplitude.
Overrange signals will be clamped. This
range is used for most logic signals.
The 50 V range is for input signals that do
not exceed 50 volts peak-to-peak amplitude.
Overrange signals will be clamped. This
range is used for general voltage
measurements including power supplies.

1 Megohm, 50 Ohms
terminating resistance
The 1 Megohm input impedance is for use
with an oscilloscope 10:1 divider probe and
for general use.
The 50 Ohm input impedance is used when
maximum trigger bandwidth is needed or
when cable reflections are a problem. It
should not be used if voltages in excess
of 7 volts r.m.s. are likely to occur.

Ext Trig # > Extensions
The Peak Hold function is used to hold
peak measurement values until reset. When
Peak Hold is Off, the measured peak values decay at a rate set by the
Averaging function.
