Discussion:
This command sets the magnitude of both floating sup-
plies to the absolute value specified. Units are amperes. The
range is 0.05 A to 0.750
A
(1.6 A at 15
V
and below) in the
high power compartment and 0.05 A to 0.40 A (0.75 A at
15
V
and below) in the standard compartment. The resolu-
tion is 0.05 A.
LLSET
Type:
Setting or query
Setting syntax:
LLSET <binary block>
Query syntax:
LLSET?
Query response:
LLSET
<
binary block>
;
Discussion:
The setting command changes all instrument settings to
the states as specified in the binary block argument. Use
this command for rapid transfer of settings. The binary block
is generated by the instrument and is not intended to be
generated or modified by the user. The query returns all
instrument settings in low level (binary) format.
The binary block format consists of the percent
(O/O) sign
(decimal 37) followed by a two byte binary count, the data
bytes and finally the checksum. The two byte binary count
(integer, most significant bit first) specifies the number of
data bytes plus the checksum byte. The checksum is the 2's
complement of the modulo 256 sum of the preceding binary
data bytes and the binary count bytes. The checksum does
not include the
O/O
sign.
