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.

Error Messages
• INITiate:CONTinuous must be set to OFF, otherwise error -213, "INIT
ignored" occurs.
• If TRIGger:SOURce is set to BUS or HOLD, error -214, "Trigger
deadlock" occurs.
• If the expected value and resolution parameters are not the same as the
current expected value and resolution settings on the specified window,
error -221, "Settings conflict" occurs.

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 lower
window's measurement.
