INTRODUCTION
The Type 7A13 Vertical Plug-In
is
a DC coupled differential
comparator with excellent common-mode rejection and medi-
um gain characteristics for medium level applications. The
Type 71413 is designed for use inTektronix 7000 series oscillo-
scopes. It may be used as a differential input preamplifier
or conventional preamplifier in addition to its use as a com-
parator.
In the differential input mode, the dynamic range allows
the application of common-mode signals up to +10 or -10
volts to be applied to the unit without attenuation. Common-
mode reiection ratio of at least 20,000:1 at DC to 100kHz
permits measurements of differential signals less than 1 mV
in amplitudeon 10volt common-mode signals.
When used as a differential comparator, the Type 7A13
has an effective offset range of 10,000 divisions.
ELECTRICAL CHARACTERISTICS
The electrical characteristics described in Table 1-1 are
valid over the stated environmental range for instruments
calibrated at an ambient temperature of +20° C to +30°
C
and after a 20-minute warmup period unless otherwise noted.
