Notes & Short
Form Commands
Notes:
1.
Parameter enclosed by [ ] - denotes factory default
2.
Parameter enclosed by ( ) - denotes power on default
3.
SCPI name ends with ? - denotes query only
4.
Unless otherwise noted SCPI command is also a query
5.
Keyword enclosed by [ ] - denotes optional use
6.
Only a configuration command that has one of its parameters enclosed by [ ] can change
its parameter setting and have this setting stored in the 4807's F
l
ash (with the *SAV
command).
7.
The format for a SCPI list is (@1,2, n) or (@ 1:n). There must be a space between the
@ and the first number and parenthesis are required. A list of numbers is separated by
commas or uses a colon to denote a range of numbers.
8.
Numeric entries conform to IEEE-488.2 section 7.7.2.4 for decimal numeric parameters.
9.
ASCII formatted data is a series of decimal values (0-255) for each byte separated by
commas. e.g. 64, 132, 8
10. The CAL:DATe commands stores the CAL:IDN and CAL:DATe parameters in the
4807's F
l
ash.
11. The CAL:DEFault command resets the Flash memory to it factory settings. Caution
- All user settings will be overridden by this command.
12. Most parameters can be output in various numeric formats (radix). The parameters
with decimal 0-255 value ranges may also be output as HEX using #h00-#hFF or
Binary using #b00000000-#b11111111. Conversely, the parameters shown with HEX
(#h) values can also be output in Decimal.
13. Serial interface always responds to every command with a response message. For
direct interface to a terminal or to a PC running a terminal emulation program, the serial
interface also supports echo-to-host and backspace characters. Echo-to-host available
on RS-232 interface only. Backspace character removes the preceding serial
character.
CTRL-E turns echo On.
CTRL-F turns echo Off. (Power-on default condition)
Note that all serial parameter changes take place after the current command prompt has
been returned to the serial host.
