1. The mnemonic
parameter used in the command sub-systems. The parameters must be entered in
the specified order. If parameters are omitted, they will default from the right. The
parameter DEFault is used as a place holder. Specifying
value unchanged.
2. When the measurement result is linear this parameter represents the number of
significant digits. When the measurement result is logarithmic 1 to 4 represents a
resolution of 1, 0.1, 0.01 and 0.001 respectively.

Description/Default
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.
The channel which the command
is implemented on. If unspecified
the current window setup is used.
However, on the E4417A, if the
window shows a ratio or difference
measurement, the upper window
defaults to channel A and the
lower window to channel B.
DEF means DEFault. This is not equivalent to the DEFault
This command queries the upper
window's relative measurement of
channel B, using the current
sensor range and a resolution
setting of 2.
