Tektronix 2230 Service Manual

Three indicators, displayed on the crt and labeled on
the bezel tag, display the condition of the options. A bat
tery backed-up CMOS memory and its battery are also
included in the options. Option commands allow saving
additional SAVE REF waveforms in the memory.

WARNING
The battery used in this device contains lithium. Do
not expose to heat Do not short terminals. See ser
vice information for complete instructions.
The communication options allow remote control of
oscilloscope functions. This remote control is accom
plished by messages sent to the instrument via either the
GPIB (IEEE-488 Standard Bus) or the RS-232-C interface.
Messages used are defined either in ANSI/IEEE-488-1978
or in the Tektronix standard on Codes, Formats, Conven
tions, and Features. Messages to the option can have one
of three purposes:
1. Query the state of the oscilloscope.
2. Query the results of measurements made.
Set the instrument operation mode.
The main purpose of the communication options is to i
allow digitized waveform data to be sent and received by
the instrument.
STANDARD FUNCTIONS,
FORMATS, AND FEATURES
The interface-function repertoire of a GPIB instrument,
in terms of interface-function subsets, is identified in
ANSl/IEEE Std 488-1978. The status of subsets applicable
to this instrument with Option 10 are listed in Table 7-1.
Both the GPIB interface and the RS-232-C interface
conform to a Tektronix standard on Codes, Formats, Con
ventions, and Features of messages sent over the bus to
communicate with other instruments equipped with a like
interface. Specific features implemented in this instrument
are listed in Table 7-2, and specific formats implemented
are shown in Table 7-3.
