Digitize Menu
Push  to access the Digitize menu. All of the parameters on the screen are
informational and are set with the digitize softkeys and . See the screen
below:

Number of Samples is a key parameter to change when you use Digitize. The
default is 1, and is changed through the Trigger Setup menus. In most
applications, change Number of Samples by setting the Triggers/Arm (Count) in
the Trigger Setup menu. There may be situations that require setting the count in
the other two trigger layers, Arm2 and Arm1 to values other than 1. If the other
layers are changed, the Number of Samples in Digitize is the product of all the
count settings in each trigger layer. For example, setting the Trigger layer
Triggers/Arm (Count) to 3 and the Arm2 Count to 1e6 gives a Number of
Samples of 3e6. The maximum Number of Samples is 10e6 with Time Stamps
Off, and 5e6 with Time Stamps On.
Digitize has these softkeys:
 (V or I): Selects the voltage or current signal path. Volts uses the HI and
LO terminals. Amps uses the A and LO terminals.
 (Range): Selects the range of the signal path. Voltage ranges are
100 mV, 1 V, 10 V, 100 V, and 1 kV. Current ranges are 10 μA, 100 μA, 1 mA,
10 mA, 100 mA, 1 A, 10 A, and 30 A (8588A only) from the front inputs. If the
rear inputs are used, the 10 A and 30 A ranges are not available.
 (Coupling, Zin): For volts, selects the input coupling and input
impedance. Available choices are DC, Auto; DC, 1 MΩ; DC, 10 MΩ; AC, 1 MΩ;
and AC 10 MΩ. For Amps,  selects the input coupling, either DC, Auto; or
AC, Auto. There may be specification differences based on the input coupling
and impedance. See Specifications.
