APERiod
Discrete
Will select the period averaged measurement function.
Period averaged can be measured continuous signals only.
In fact, this is the inverse function of frequency and
therefore, gate time determines the resolution of the
reading. Reduce the gate time when you want to accelerate
the reading process however, always make sure that the
period of the signal is smaller than the gate time setting.
PULSe
Discrete
Will select the pulse width measurement function. Pulse
width can be measured on either continuous or non-
repetitive signals. Since the width of the signal is directly
proportional to the gating time, the number of displayed
digits decreases proportionally to the pulse width of the
signal. The best resolution in period measurements is 10
ns.
ITOTalize
Discrete
Will select the totalize measurement function. In this mode,
the gate opens when the first valid signal is sensed at the
counter input and remains open until programmed
otherwise. Pulse are counted and displayed continuously
until intervened externally. The counter can accumulate 8
digits before it will overflow. An overflow indication is
available.
Response
The 3152B returns FREQ, PER, APER, PULS, or ITOT depending on the current measurement function
setting.

Description
Programs the display time mode for the counter/timer. The two modes are normal for continuous display
readings and hold for single reading after arming the counter input.

Description
NORMal
Discrete
NORM
Will select the continuous reading mode. In this case, the
counter input is self-armed, which means that every valid
signal that is sensed at the trigger input connector will be
counted and measured processed and results placed on
the interface port.
HOLD
Discrete
Will select the single reading mode. In this case, the
counter input is armed first and the first valid signal that is
sensed at the trigger input connector will be counted and
measured and its result processed and placed on the
interface port.
Response
The 3152B returns NORM, INV, or COMP depending on the current polarity setting
