parameter. Do not use spaces within a parameter,
or within a number.

Expressions Do not use expressions as parameters. An
Units Accepted units in command parameters are:
When a command has more than one parameter,
separate the parameters with commas. For
example: "OUT 1 V, 100 HZ".
Parameters may have up to 255 significant figures.
Exponents may range from -32000 to
+32000. The useful range for 5720A programming
is ± 2.2 E-308 to ± 1.8 E308.
All lower case letters are converted to upper case
except in quoted strings.
Avoid using extra parameters. Too many
parameters will cause a command error.
Null parameters will cause a command error (e.g.,
adjacent commas in "CLOCK 133700, ,071787").
example of an expression is "(4+2*13)".

Commands
Terminators Terminators sent by the 5720A: LF with EOI.
Responses The responses described in the command table are
To combine commands in one statement, use a
semicolon (;). For example, instead of using these
two statements:
20 PRINT @3,"OUT 100 MV" ! Select 100 mV dc
30 PRINT @3,"OPER" ! Activate the output
You can accomplish the same with this single line:
20 PRINT @3,"OUT 100 MV ; OPER"
Terminators received by the 5720A: LF or any
character with EOI
correct for IEEE-488 remote control, and for serial
remote control in "COMPUTER" mode. In serial
remote control in "TERMINAL" mode, responses
contain more descriptive text intended for an
operator using a terminal interactively.

Serial Poll Status Byte and SRE Bit Definitions
76543210
0 RQS ESB MAV EAV ISCB 0 0
MSS
RQS For IEEE-488 remote control: Requesting service. The
RQS bit is set to 1 whenever bits ESB, MAV, EAV, or
ISCB change from 0 to 1 and are enabled (1) in the
SRE. When RQS is 1, the 5720A asserts the SRQ
control line. Perform a serial poll to read this bit to see if
the 5720A is the source of an SRQ. (A serial poll also
clears the RQS bit.)
MSS For serial remote control: Master summary status. Set to
1 whenever bits ESB, MAV, EAV, or ISCB are 1 and
enabled (1) in the SRE. This bit can be read using the
*STB? command.
ESB Is set to 1 when one or more enabled ESR bits are 1.
MAV Message available. The MAV bit is set to 1 whenever
data is available in the 5720A’s IEEE-488 interface
output buffer.
EAV Error (fault) available. A fault has occurred and a fault
code is available to be read from the fault queue by
using the FAULT? query.
ISCB One or more enabled ISCR bits are 1.

PON 0 CME EXE DDE QYE 0 OPC
PON Power on. This bit is set to 1 if the power has been
cycled since the last time the ESR was read.
CME Command error (fault). The IEEE-488 interface
encountered an incorrectly formed command.(The
command FAULT? fetches the earliest fault code in
the fault queue, which contains codes for the first 15
faults)
EXE Execution error (fault). A fault occurred while the
5720A tried to execute the last command. This could
be caused, for example, by a parameter being out of
range. (The command FAULT? fetches the earliest
fault in the fault queue, which contains codes for the
first 15 faults that have occurred.)
DDE Device-dependent error (fault). A fault related to a
device-dependent command has occurred. An
example would be attempting to execute "OUT
1000000V", which is outside the range of the 5720A.
(The command FAULT? fetches the earliest fault in the
fault queue, which contains codes for the first 15 faults
that have occurred.)
QYE Query error (fault). The 5720A was addressed to talk
when no response data was available or appropriate,
or when the controller failed to retrieve data on the
output queue.
OPC Operation complete. All commands previous to
reception of a *OPC command have been executed,
and the interface is ready to accept another message.
