Options-2445A/2455A Service
OPTION 05
Option
05
(TV)
simplifies triggering
and
viewing of telev-
ision signals.
The
option
adds
TV
(back-porch) clamp cir-
cuitry to the
Channel
2 input
and
TV
trigger coupling
modes,
allowing selection of either horizontal or vertical
sync pulses to obtain horizontal-line-sync or field-sync
pulse
triggering. This option permits triggering
on
a
specific
line
number within a
TV
field
and
provides sync
polarity switching for either sync-negative or sync-positive
composite video signals.
OPTIONS 06 AND 09
Options
06
(Counter/Timer/Trigger)
and
09
(Counter/Timer/Trigger with Word Recognizer) allow preci-
sion
time-interval measurement, event
and
frequency
7-2
counting, delay-by-events triggering,
and
logic triggering.
The
17-bit Word Recognizer probe of Option
09
extends
the capabilities of these functions.
OPTION 10
Option 1 0 allows the instrument to
be
remotely con-
trolled
and
queried using a standard interface system.
The
interface implemented conforms to the specifications con-
tained
in
IEEE Standard Digital Interface for Programmable
Instrumentation (ANSI/IEEE
Std
488-1978), commonly
referred to
as
the
General
Purpose Interface Bus
(GPIB).
It
also complies with a Tektronix Standard relating to GPIB
Codes,
Formats, Conventions
and
Features.
