Item Description/Default
resolution A numeric value for the resolution. If it is
unspecified the current resolution setting is
used. If a value is entered it should correspond to
the current resolution setting otherwise an error
occurs.
source list The channel which the command is implemented
on. If unspecified the current window setup is
used. However, on the N1912A, if the window
shows a ratio or difference measurement, the
upper window defaults to Channel A and the
lower window to Channel B.

The mnemonic DEF means DEFault. This is not equivalent to the DEFault parameter used in the
command sub-systems. The parameters must be entered in the specified order. If parameters are
omitted, they default from the right. The parameter DEFault is used as a place holder. Specifying
DEF leaves the parameter value unchanged.

When the measurement result is linear this parameter represents the number of significant
digits. When the measurement result is logarithmic 1 to 4 represents of 1, 0.1, 0.01 and 0.001
respectively.
occurs. A measurement is valid after it has been initiated. It becomes
invalid when either a reset occurs or any measurement parameter, for
example frequency, is changed.
This command queries the upper
window/upper measurement relative
measurement of Channel B, using the
current sensor range and a resolution
setting of 2.
