displays only the real (resistive) portion of the measured data
on a Cartesian format. This is similar to the linear magnitude
format, but can show both positive and negative values. It is
primarily used for analyzing responses in the time domain, and
also to display an auxiliary input voltage signal for service
purposes.
Press this key after selecting the file associated with port 1
error correction for adapter removal calibration.
Press this key after selecting the file associated with port 2
error correction for adapter removal calibration.
provides access to the recall cal sets menu. This softkey also
brings up the internal (or external if internal not used) disk
drive file directory.
recalls the previously saved modified version of the color set.
This key appears only when a color set has been saved.
recalls the instrument state saved in register 1.
recalls the instrument state saved in register 2.
recalls the instrument state saved in register 3.
recalls the instrument state saved in register 4.
recalls the instrument state saved in register 5.
recalls the instrument state saved in register 6.
is used in conjunction with sequencing, to return the
instrument to the known preset state without turning off the
sequencing function. This is not the same as pressing the Lpreret
key: no preset tests are run, and the HP-IB and sequencing
activities are not changed.
provides access to the Receiver Cal Menu.
selects the display reference line for color modification.
selects the reference line for printer color modification.
sets the position of the reference line on the graticule of a
Cartesian display, with 0 the bottom line of the graticule and 10
the top line. It has no effect on a polar or Smith display. The
reference position is indicated with a small triangle just outside
the graticule, on the left side for channel 1 and the right side
for channel 2.
changes the value of the reference line, moving the
measurement trace correspondingly. In polar and Smith chart
formats, the reference value is the same as the scale, and is the
value of the outer circle.
