Special Numeric Values
The texts MINimum, MAXimum, DEFault, UP and DOWN are interpreted as special
numeric values. In case of a query, the numeric value is returned.
●
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 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
response.
●
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 val-
ues.
Example:
Setting command:
SENSe:FREQuency:STOP MAXimum
Query:
SENSe:FREQuency:STOP?
Response: 3.5E9

Boolean Parameters
Boolean parameters represent two states. The ON state (logically true) is represented
by ON or a numerical value unequal to 0. The OFF state (logically untrue) is represen-
ted by OFF or the numerical value 0. The numerical values are provided as response
for query.
Example:
Setting command:
CALCulate:MARKer:STATe ON
Query:
CALCulate:MARKer: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 provided.
