EXECUTE SINGLE
Starts a single signal output. This menu item is displayed only with MODE =
SINGLE.
EXT TRIG SLOPE
Selects the polarity of an external trigger signal at connector TRIG. This
external trigger signal generates a trigger event. This setting has an effect on
modes GATED (HIGH/LOW), EXT-AUTO and EXT-SINGLE (POS/NEG).
FILTER
Configuration of reconstruction filters for signal paths I and Q.
OFF
Output of unfiltered I/Q signals
2.5 MHz
Loop in of the internal 2.5 MHz lowpass filter.
25 MHz
Loop in of the internal 25 MHz lowpass filter
EXT
Loop in of external bandpass filters for the I and Q
channel. For a detailed specification of the filter see
AMIQ manual, section Signal Inputs and Outputs.
Note
:
With external filtering it has to be made sure that a filter is
connected to both filter inputs I and Q on the rear of AMIQ. The
two signal outputs can be switched off completely during external
filtering provided that no filter is connected to the corresponding
filter input.
