Option 05; Options 06 And 09; Option 10; Option 11 - Tektronix 2445A Service Manual

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.
