N (nano)
Example:
SENSe:FREQ:STOP 1.5GHz = SENSe:FREQ:STOP 1.5E9
Some settings allow relative values to be stated in percent. According to SCPI, this unit
is represented by the PCT string.
Example:
HCOP:PAGE:SCAL 90PCT
Special Numeric Values
The following mnemonics are special numeric values. In the response to a query, the
numeric value is provided.
●
MIN and MAX: denote the minimum and maximum value.
●
DEF: 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 and DOWN: increases or reduces the numeric value by one step. The step
width can be specified via an allocated step command for each parameter which
can be set via UP and DOWN.
●
INF and NINF: INFinity and negative INFinity (NINF) represent the numeric values
9.9E37 or -9.9E37, respectively. INF and NINF are only sent as instrument respon-
ses.
●
NAN: Not A Number (NAN) represents the value 9.91E37. NAN is only sent as a
instrument 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 miss-
ing values.
Example:
Setting command: SENSe:LIST:FREQ MAXimum
Query: SENS:LIST:FREQ?
Response: 3.5E9
Queries for special numeric values
The numeric values associated to MAXimum/MINimum/DEFault can be queried by
adding the corresponding mnemonic after the quotation mark.
Example: SENSe:LIST:FREQ? MAXimum
Returns the maximum numeric value as a result.
Boolean Parameters
Boolean parameters represent two states. The "ON" state (logically true) is represen-
ted by "ON" or a numeric value 1. The "OFF" state (logically untrue) is represented by
"OFF" or the numeric value 0. The numeric values are provided as the response for a
query.
