displays the logarithmic magnitude value and the phase of
the active marker in Polar or Smith chart format.
Magnitude values are expressed in dB and phase in
degrees. This is useful as a fast method of obtaining a
reading of the log magnitude value without changing to
log magnitude format.
displays the current value of the loop counter and allows
you to change the value of the loop counter. Enter any
number from 0 to 32767 and terminate with the key.
The default value of the counter is zero. This command
should be placed in a sequence that is separate from the
measurement sequence. For this reason: the measurement
sequence containing a loop decision command must call
itself in order to function. The
command must be in a separate sequence or the counter
value would always be reset to the initial value.
(Sequence Filenaming) inserts the string “[LOOP]” into the file name.
accepts a power loss value for a segment in the power
meter cal power loss list. This value, for example, could be
the difference (in dB) between the coupled arm and
through arm of a directional coupler.
presents the power loss/sensor lists menu. This menu
performs two functions:
• Corrects coupled-arm power loss when a directional
coupler is used to sample the RF output.
• Allows calibration factor data to be entered for one or
two power sensors.
Each function provides up to 12 separate frequency points,
called segments, at which the user may enter a different
power loss or calibration factor. The instrument
interpolates between the selected points. Two power
sensor lists are provided because no single power sensor
can cover the frequency range of the network analyzer.
(Option 010 only) sets the transform to low pass impulse
mode, which simulates the time domain response to an
impulse input.
(Option 010 only) sets the transform to low pass step
mode, which simulates the time domain response to a step
input.
