Numeric parameters
The TOS5300 Series uses the following five parameter types.
Special form numeric parameters
The special form numeric parameters MINimum and MAXimum can be used as substitutes for the
actual maximum and minimum values when the parameter is numeric.
The following example sets the volume level of the buzzer that is sounded when a PASS judgment
occurs to the minimum value.
SYSTem:CONFigure:BEEPer:VOLume:PASS MINimum
You can query the minimum and maximum values for most parameters.
SOURce:VOLTage:PROTection? MAXimum
Measurement units
The default measurement units are listed below. Commands are accepted even if measurement
units are not specified.
•
A (current)
•
V (voltage)
•
OHM (resistance)
•
S (seconds
•
HZ (frequency)
The following optional prefixes are supported. If you use optional prefixes, specify the
measurement unit.
•
G (giga)
•
MA (mega)
•
K (kilo)
•
M (milli)
•
U (micro)
To enter “μ” in a parameter, use “U.” When the measurement unit is “Hz” or “OHM” and you enter
“M” in the parameter, the unit will be “mega.”

Description
NR1
Represents an integer value.
1
1
Details are given in the “IEEE 488.2 Standard Digital Interface for Programmable Instrumentation.”
NR2
Represents a real number in floating-point format.
1
NR3
Represents a real number in scientific notation.
1
If 380 is returned in the response data, it is returned as +3.80000+E02. Five decimal places
are used.
NRf
NRf is a generic term that includes NR1, NR2, and NR3.
Numeric
Represents values such as the decimal point, optional prefixes, and measurement units.
Numbers are expressed the same as NRf.
MINimum and MAXimum are available as substitutes for declaring certain values.
You can also use units such as V, A, and S in numeric parameters.
If a value that cannot be assigned is entered, the TOS5300 Series rounds the value to the
closest possible value.
Example:
SYSTem:CONFigure:BEEPer:VOLume:PASS 2.0
SYST:CONF:BEEP:VOL:PASS must be set to a value from 0.0 to 1.0, so even if you attempt to
set the value to 2.0, it will be set to 1.0.
The unit symbols in the International System of Units contain lowercase characters. The IEEE
standard uses uppercase characters. SCPI commands are not case sensitive.
