Tektronix 2230 Operator's Manual

ADVANCED FUNCTION MENU
{for the 2230 only)
The following functions are available as part of the
ADVANCED FUNCTIONS Menu on 2230 instruments con-
taining either the GPIB or the RS-232-C option.
REFERENCE-Allows a non-volatile SAVE REF
memory to be copied, deleted, or protected.
COPY-Selects and copies one non-volatile SA VE
REF memory to another SAVE REF memory.
Waveforms stored in the lettered extended memory
locations (REFA through REFZ) must be moved to
one of the numbered SAVE REF memory locations
to be displayed. Waveform data to be retrieved
from or written to an extended memory location
must go through a numbered SAVE REF memory.
DELETE-Selects a non-volatile SAVE REF
memory and erases the stored data if not locked.
PROTECT -Selects memory space to lock or
unlock. Locked memory locations cannot be
overwritten or deleted. Via the Communications
interface, extended memory locations may be per-
- - manently protected to prevent them from being
overwritten by the UNLOCK or DELETE
menu functions.
COMM-Allows the selection of parameters for
optional communications options, when they are
present.
DATA-Selects the data-coding format (ASCII,
HEX, or BINARY), source or destination target of
the data (ACQ, REF1, REF2, REF3 or REF4), and
channel selection (CH1 or CH2) for
data transmissions.
STOP BITS-Selects the number of stop bits for
RS-232-C data transmissions. (Stop bits are
selected by interface command in the 2220 and
2221.) The usual choice for stop bits is 1, but some
printers/plotters require two stop bits for some
baud rates.
FLOW-Sets the data flow control over the inter-
face ON and OFF. Binary waveform information
cannot be sent with FLOW ON.

NON-VOLATILE EXTENDED MEMORY
{for the 2230 only)
When either Communications option is installed in the
2230 DSO, extra battery-backed memory is also installed.
Waveforms stored in the extra memory may be protected
from overwriting or deleting (locked) using the Advanced
Functions menu. Commands that are available via the
communications interface can also lock that memory
space. Memory spaces may be also made "permanent" via
the Communications interface. Permanent waveforms
cannot be overwritten, unlocked, or deleted by the opera-
tor with the Advanced Functions menu.
The extra memory provides 26 Kbytes of non-volatile
waveform storage space. The memory is divided into
1 Kbyte locations labeled REFA through REFZ, but the
number of actual waveforms that may be stored depends
on the acquired waveform record length (1024 bytes or
4096 bytes) and acquisition mode (normal or average).
Averaged waveforms require two bytes for each point so
that an averaged 1 K waveform needs 2 Kbytes of non-
volatile SAVE REF storage and an averaged 4 K
waveform needs 8 Kbytes. Specifications for the non-
volatile Extended Memory are given in Table 7-1.
OPTION 10 GPIB
OPERATORS INFORMATION
The GPIB Communications Option complies with
ANSI/IEEE Standard 488-1978. All other specifications for
the instrument (including the performance conditions) are
identical to those specified in "Specification" in Section 1
of this manual.
Standard Functions, Formats, and Features
The interface-function capabilities of a GPIB instrument,
in terms of interface-function subsets, are identified in
ANSI/IEEE Std 488-1978. The status of subsets applicable
to this instrument with Option 10 are listed in Table 7-2.
The GPIB interface conforms to the Tektronix standard
on Codes, Formats, Conventions, and Features of
messages sent over the bus to communicate with other
GPIB instruments. Specific format choices implemented in
this instrument are listed in Table 7-3; specific features
implemented are shown in Table 7-4.
