Technical data

4-23
Hardkey and Softkey Reference
RANGE 6 -75 TO -50. selects power range 10 when in manual power range.
RANGE 7 -85 TO -60. selects power range 11 when in manual power range.
RAW ARRAY on OFF. specifies whether or not to store the raw data (ratioed and averaged) on disk with the instrument
state.
RAW OFFSET On Off. selects whether sampler and attenuator offsets are ON or OFF. By selecting raw offsets OFF, a full
two port error correction can be performed without including the effects of the offsets. It also saves substantial time at
recalls and during frequency changes. Raw offsets follow the channel coupling. This softkey is used with "Take4" mode.
Refer to the examples in the programmer’s guide.
Re/Im MKR. when in the smith marker menu, Re/Im MKR displays the values of the active marker on a Smith chart as a
real and imaginary pair. The complex data is separated into its real part and imaginary part. The first marker value
given is the real part M cos θ, and the second value is the imaginary part M sin θ, where M =magnitude. When in the
polar marker menu, Re/Im MKR displays the values of the active marker as a real and imaginary pair. The complex
data is separated into its real part and imaginary part. The first marker value given is the real part M cos θ, and the
second value is the imaginary part M sin θ, where M = magnitude.
READ FILE TITLES. searches the directory of the disk for file names recognized as belonging to an instrument state, and
displays them in the softkey labels. No more than five titles are displayed at one time. If there are more than five,
repeatedly pressing this key causes the next five to be displayed. If there are fewer than five, the remaining softkey
labels are blanked.
READ SEQ FILE TITLS. is a disk file directory command. Pressing this softkey will read the first six sequence titles and
display them in the softkey labels. These sequences can then be loaded into internal memory. If READ SEQ FILE
TITLS is pressed again, the next six sequence titles on the disk will be displayed. To read the contents of the disk
starting again with the first sequence: remove the disk, reinsert it into the drive, and press READ SEQ FILE TITLS.
REAL. 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.
RECALL CAL PORT 1. Press this key after selecting the file associated with port 1 error correction for adapter removal
calibration.
RECALL CAL PORT 2. Press this key after selecting the file associated with port 2 error correction for adapter removal
calibration.
RECALL COLORS. recalls the previously saved modified version of the color set. This key appears only when a color set
has been saved.
RECALL KEYS. accesses two recall keys which allows you to set the recall keys menu as the initial menu displayed when
Save/Recall is pressed or select specific registers to recall.
RECALL KEYS MENU. provides access to the recall keys menu where specific registers can be recalled.
RECALL KEYS on OFF. presents the recall keys menu as the initial menu when Save/Recall has been pressed.
RECALL REGX. recalls the instrument state saved in register 1, 2, 3, 4, 5, 6, or 7.
RECALL STATE. when the internal disk is selected in the Save/Recall menus this key recalls the instrument state that is
highlighted in the directory.
RECEIVER CAL. provides access to the Receiver Cal Menu.
RECEIV OUT CAL/OPT. manually selects the switch position for the lightwave test set, which is either in the external
optical path position or the internal calibration path position. If the COUPLED SW is set to ON, the lightwave test set
switch position will revert back to the default position at the end of the sweep.
REF LINE. selects the display reference line for color modification.
REF LINE [ ]. selects the reference line for printer color modification.
REFERENCE POSITION. 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.
REFERENCE VALUE. 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.
REFL: FWD S11 (A/R). defines the measurement as S
11
, the complex reflection coefficient (magnitude and phase) of the
test device input.
