7.4.5.2 7.4.5.2 7.4.5.2 7.4.5.2 Discrete Parameters Discrete Parameters Discrete Parameters Discrete Parameters
Discrete parameters are used in order to program setups that have a limited amount
of values. You have a long and a short form for command key words. Upper and
lower case can be mixed. Replies to queries are always only emitted in long form and
in upper case.
Example:
:PEAK:MODE FAST
7.4.5.3 7.4.5.3 7.4.5.3 7.4.5.3 Boolean Parameters Boolean Parameters Boolean Parameters Boolean Parameters
Boolean parameters represent a single condition that is either true or untrue. As an
untrue condition the gaussmeter accepts "OFF" or "0". As a true condition the gauss-
meter accepts "ON" or "1". If a Boolean setup is interrogated, the device always emits
"0" or "1".
Example:
:DISP:BARG ON
:DISP:BARG?
Answer:1<cr><lf>
7.4.5.4 7.4.5.4 7.4.5.4 7.4.5.4 Chara Chara Chara Character String Parameter cter String Parameter cter String Parameter cter String Parameter
Character string parameters can, in principle, contain a limited amount of ASCII-
characters. A character string must begin and end with either an apostrophe (
'
) or a
quotation mark (
"
), with the same character at the beginning and at the end of the
character string. The delimiter can be used within the character string by keying it in
twice in a row without blank.
Example:
:PROB:IDEN "PART x"
:PROB:IDEN 'PART x'
7.4.5.5 7.4.5.5 7.4.5.5 7.4.5.5 Entry Entry Entry Entry Ending Ending Ending Endingssss
Program messages that are sent to the gaussmeter must end with an
<LF>
character.
Likewise a
<CR>
character followed by an
<LF>
character is accepted. By terminating
a message, the current path is always set back to the root directory.
