displays the log magnitude format. This is the standard
Cartesian format used to display magnitude-only measurements
of insertion loss, return loss, or absolute power in dB versus
frequency.
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 Lxl] 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 .commmd must call itself in order to function. The
counter value would always be reset to the initial value.
inserts the string "[LOOP]" into the lilename.
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
n
used to sample the RF output.
Allows calibration factor data to be entered for one or two
n
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
possible with an HP 8719D/20D/22D.
selects low band as the calibration standard load.
(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.
sets the lower limit value for the start of the segment in a
limit line list. If an upper limit is specified, a lower limit must
also be defined. If no lower limit is required for a particular
measurement, force the lower limit value out of range (for
example -500 dl3).
