specified at a particular value plus or minus an equal tolerance.

For example, a device may be specified at 0 dl3 &3 dl3. Enter the delta limits as 3 dl3 and the middle value as 0 dl3.

(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 particuhxrly 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 fIlea The number of directory hles 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. !I’his is used in conjunction with the HP-IB address of the disk drive, and the volume number, to gain access to a specific area on a disk. The access hierarchy is HP-IB 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.

provides access to a series of menus for instrument and active channel display functions. The llrst 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.

activates both forward and reverse calibration measurements from selected calibration menus
