sets the limits an equal amount above and below a
specified middle value, instead of setting upper and lower
limits separately. This is used in conjunction with
or , to set limits
for testing a device that is specified at a particular value
plus or minus an equal tolerance.
For example, a device may be specified at 0 dB ±3 dB.
Enter the delta limits as 3 dB and the middle value as
0dB.
(Option 010 only) amplitude demodulation for CW time
transform measurements.
(Option 010 only) turns time domain demodulation off.
(Option 010 only) phase demodulation for CW TIME
transform measurements.
lets you specify the number of directory files to be
initialized on a disk. This is particularly useful with a
hard disk, where you may want a directory larger than the
default 256 files, or with a floppy disk you may want to
reduce the directory to allow extra space for data files. The
number of directory files must be a multiple of 8. The
minimum number is 8, and there is no practical maximum
limit. Set the directory size before initializing a disk.
specifies the number of the disk unit in the disk drive that
is to be accessed in an external disk store or load routine.
This is used in conjunction with the GPIB address of the
disk drive, and the volume number, to gain access to a
specific area on a disk. The access hierarchy is GPIB
address, disk unit number, disk volume number.
displays response and stimulus values for all markers that
are turned on. Available only if no marker functions are
on, for example .
provides access to a series of menus for instrument and
active channel display functions. The first menu defines
the displayed active channel trace in terms of the
mathematical relationship between data and trace
memory. Other functions include auxiliary channel
enabling, dual channel display (overlaid or split), display
intensity, color selection, active channel display title, and
frequency blanking.
displays the current measurement data for the active
channel.
leads to a series of service tests for the display.
