Binary, Decimal, Hexadecimal, and Octal Formats
Command values may be entered using a binary, decimal, hexadecimal, or octal format. When
the binary, hexadecimal, or octal format is used, their values must be preceded with the
proper identifier. The decimal format (default format) requires no identifier and the signal
generator assumes this format when a numeric value is entered without one. The following
list shows the identifiers for the formats that require them:
• #B identifies the number as a binary numeric value (base-2).
• #H identifies the number as a hexadecimal alphanumeric value (base-16).
• #Q identifies the number as a octal alphanumeric value (base-8).
The following are examples of SCPI command values and identifiers for the decimal value 45:
#B101101 binary equivalent
#H2D hexadecimal equivalent
#Q55 octal equivalent
NOTE While the commands accept the different numeric formats, the queries will
return all values in decimal.
The following example sets the RF output power to 10 dBm (or the equivalent value for the
currently selected power unit, such as DBUV or DBUVEMF) using the hexadecimal value 000A:
:POW #H000A
A unit of measure, such as DBM or mV, will not work with the values when using a format other
than decimal.
