Model 5328A
Applications
4-20.
InT.]. A>BandT.I. AVG A-B with the rear panel ARM switch OFF, the counter is armed
by the run down of the SAMPLE RATE control. With the rear panel ARM switch ON, T.1. A~B and
T.I1. AVG AB are armed by an event at the C input (if Option 030 channel C is installed). For T.1.
AVG A-B, only one arming signal is required per average measurement (i.e., the counter doesn't
need to be armed prior to each individual time interval in the time interval measurement).
4-21.
TOTALIZING MEASUREMENTS
4-22.
Two totalizing functions are available: START A and Events at C during the time interval
from A to B (Events C, AB). InSTART A, the number of counts at the A input are totalized if N=1.
If N is greater than 1, A/N is totalized and the scaled output is available at the (TB OUT) rear panel
connector.
4-23.
With Option 030 channel C, the events C, A—B function allows the number of events at
the C input to be totalized during a synchronized time interval defined by inputs to channels A
and B. A synchronized time interval means that the actual time interval during which events are
totalized is a multiple of 100 ns (or 10 ns with Option 040) and is synchronized to the counter's
clock
LIVER.
4-24.
DVM MEASUREMENTS
4-25.
Option 020
4-26.
Three modes of Option 020 voltmeter operation may be selected:
DVM, READ A, or
READ B. In the READ A and READ B modes, the digital voltmeter measures the trigger level of
channel A or B, regardless of the setting of the FUNCTION switch. To return control to the
FUNCTION control switch, the DVM control must be switched back to DVM 100V RANGE. When
the digital voltmeter is in DVM 100V RANGE and the FUNCTION control is in DVM, the digital
voltmeter measures the external voltage applied to its input connector.
4-27.
The trigger level read by the voltmeter in READ A or READ B modes must be multiplied by
the setting of the universal module's attenuator switch if using the standard universal module.
The trigger level represents the center of the hysteresis band. If using the Option 040 universal
module, the trigger level read by the DVM must be multiplied by 10 if the universal module
attenuator position is in the X20 position (the X2 position is automatically accounted for) if the
FUNCTION control is in T.1. AB or T.1. AVG A-B. The trigger level represents the top of the
hysteresis band for +slope and the bottom of the hysteresis band for -slope. In any other function,
the trigger level represents the middle of the hysteresis band.
4-28.
The DVM'has a 0 to 125V range and allowable measurement times for 1 ms to 10s. These
times are determined by the setting of the RESOLUTION switch according to the following table.

The Option 020 DVM is single ended. One of the input terminals is grounded. Levels over 125V dc
are read as 125V dc. Maximum input is +500V dc.
4-29.
Option 021
4-30.
Three modes of Option 021 voltmeter operation may be selected: DVM, READ A or READ
B. When a mode is selected (by depressing the appropriate pushbutton), the digital voltmeter
measures the trigger level of channel A or B, regardless of the setting of the FUNCTION switch. A
