Repeatability

When the pulse card operates under the same environmental conditions and with the same
settings, the value of a parameter will lie within a band inside the accuracy window (see
11-38). Repeatability defines the width of this band.

PIV-Q user libraries

The user library UTMs used in the PIV-Q package are documented as follows:
• "DualPulseulib UTM descriptions" on page 11-50
control the Dual Card pulse generator through the 4205-PCU (Pulse Combiner Unit). These
UTMs are used in the 4200-PIV-Q package.
• "QPulseIVulib UTM descriptions" on page 11-62
Model 4200-PIV-Q package.

DualPulseulib UTM descriptions

The DualPulseulib UTMs are used to control the Dual Card pulse generator through the 4205-PCU
(Pulse Combiner Unit). The Pulse Combiner Unit is supplied with the 4205-PIV-Q and provides
dual pulse control of two adjacent 4205-PG2 pulse generators. For more information, refer to
Section 12 of the Reference Manual and the PIVQ application in the Applications Manual.
The modules contained in the dual pulse user library are listed in
information following the table.

Dual pulse control is by a usrlib, not within LPTLib. LPTLib commands such as devclr
and devint do not apply to the Dual Card pulse generator. To initialize the Dual Card
pulse generator, use the
