RS232 Remote Command Formats
Serial input to the instrument is buffered in an input queue which is filled, under interrupt, in a
manner transparent to all other instrument operations. This queue contains raw (un-parsed)
command data which is taken, by the parser, as required. Commands (and queries) are executed
in order and the parser will not start a new command until any previous command or query is
complete.
Commands (and queries) must be sent as specified in the command list and must be terminated
with the command terminator code 0AH (Line Feed, LF). Note that parameters are separated
from the command header by one space (20H) and multiple parameters are separated by
commas (2CH).
Responses to commands or queries are sent immediately; there is no output queue. The
controller must wait for the response to a command or query before the next command or query
is sent.
The instrument responds to the controller after every command either with 'OK' if the command
was completed successfully, or with 'ERRnn' if the command was not accepted; nn is the error
number, see list at the end of this section. The instrument responds to the controller after every
query as specified in the commands list. In all cases each response is terminated by 0DH
(Carriage Return, CR) followed by 0AH (Line Feed, LF).

except in command identifiers. e.g. '*C LS' is not equivalent to '*CLS'.
The high bit of all characters is ignored.
The commands are case insensitive.

Command List

This section lists all commands and queries implemented in this instrument. The commands are
listed in alphabetical order within the function groups.
The following nomenclature is used:
<rmt>
<nrf>
<nr1>
Measurement Set-up Commands
BIASOFF
BIASON
FREQ <nr1>
FUNC <nr1>
18
is defined as character codes 00H to 20H inclusive.
<RESPONSE MESSAGE TERMINATOR>
A number in any format. e.g. 12, 12·00, 1·2 e1 and 120 e-1 are all
accepted as the number 12. Any number, when received, is converted to
the required precision consistent with the use then rounded up to obtain
the value of the command.
A number with no fractional part, i.e. an integer.
Sets internal bias off.
Sets internal bias on.
Sets the frequency as follows:
<1> sets 100Hz or 120Hz as determined by internal hardware link.
<2> sets 1kHz.
<3> sets 10kHz.
Sets the measurement function as follows:
<0> sets Auto
<1> sets R + Q
<2> sets L + Q
<3> sets C + D
<4> sets C + R
