Querying

Parameter Settings Unless otherwise noted in the refere nce section, para meter settings can b e
queried by adding a question mark (?) to the command whic h se t the
parameter. For example:
INP:IMP 50
sets the impedance of the ’Input 1’ port to 50Ω. The value can be queried by
executing:
INP:IMP?
The MINimum or MAXimum value of a paramet er is determined as
follows:
INP:IMP? MIN
INP:IMP? MAX
