Operating Manual 1302.6163.12 - 03
In the case of a query, the numerical value is provided.
Example:
Setting command:
SENSe:FREQuency:STOP MAXimum
Query:
SENSe:FREQuency:STOP?
Response:
3.5E9
MIN/MAX
MINimum and MAXimum denote the minimum and maximum value.
DEF
DEFault denotes a preset value which has been stored in the EPROM. This value
conforms to the default setting, as it is called by the *RST command
UP/DOWN
UP, DOWN increases or reduces the numerical value by one step. The step width
can be specified via an allocated step command (see annex C, List of Commands)
for each parameter which can be set via UP, DOWN.
INF/NINF
INFinity, Negative INFinity (NINF) Negative INFinity (NINF) represent the
numerical values -9.9E37 or 9.9E37, respectively. INF and NINF are only sent as
device responses.
NAN
Not A Number (NAN) represents the value 9.91E37. NAN is only sent as device
response. This value is not defined. Possible causes are the division of zero by
zero, the subtraction of infinite from infinite and the representation of missing
values.
Boolean Parameters
Boolean parameters represent two states. The ON state (logically true) is repre-
sented by ON or a numerical value unequal to 0. The OFF state (logically untrue) is
represented by OFF or the numerical value 0. 0 or 1 is provided in a query.
Example:
Setting command:
DISPlay:WINDow:STATe ON
Query:
DISPlay:WINDow:STATe?
Response:
1
Text
Text parameters observe the syntactic rules for key words, i.e. they can be entered
using a short or long form. Like any parameter, they have to be separated from the
header by a white space. In the case of a query, the short form of the text is pro-
vided.
Example:
Setting command:
INPut:COUPling GROund
Query:
INPut:COUPling?
Response:
GRO
