Menu Item Function

(Type) Selections (SCPI cmd)

Range Pulse, Mod & Stat Selects the low or high sensitivity range

(Toggle) 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.

SENSe[3/4]:RANGe {5, 50} (volts/Div)

Impedance Pulse, Mod & Stat Select external trigger channel input

(Toggle) 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.

SENSe[3/4]:IMPedance {1, 50}

(1Mohm or 50 Ohm)

Peak Hold Pulse & Mod Turns Peak Hold function on and off Figure 4-23.

(Toggle) Off, On 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.
