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
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
window's measurement of
channel A, using an expected power
level of -70 dBm and a resolution
setting of 1.
