- 6 DIGIT LCD
- VARIABLE: PULSE HEIGHT, PULSE WIDTH, & PULSE RATE
Figure 1: PV-R2
The most frequently used method for calibration
of a pulse counting radiation monitor is via a pulse generator followed
by a ``touch up'' on a radiation calibration course. However,
``coincidence loss'' at high counting rates based on randomness
of radiation pulses is not matched by the evenly spaced output of
the usual ``pulser''.
The PV-R2 Random
Pulse Generator corrects this deficiency and results in
little or no ``touch up'' in the final radiation course checkout.
DESCRIPTION: The PV-R2 Random
Pulse Generator furnishes pulses whose width can be set to match the
effective width of the GM or scintillation pulse in the counting system.
Pulse height, Pulse frequency and Pulse width are all settable. The
true mean value of the Pulse rate can be traced to an NIST standard.
This true mean Pulse rate is displayed on a 6 digit LCD. The Pulse
output is protected against high voltage which may be present on the
connector of the counter being checked.
