Option FHD
Description and Operation
Option FHD is a removable hard-disk drive at the front of the instrument. With
this option the hard drive at the rear of the instrument and the floppy drive at the
front of the instrument are not available.
All instrument functions that require the floppy drive are unavailable. All
instrument functions that require a hard disk use the removable hard drive
located in the front panel. All other instrument functions remain the same as the
standard instrument.
CAUTION. Do not lift or support the instrument by the hard-drive handle.
Moving the Disk
If you move the hard disk to another instrument, you must perform a signal path
compensation.
1. To compensate the signal path, select Utilities and then Instrument Calibra-
tion.
Disk Removal
2. Read the Calibration Instructions.
3. Press the Calibrate button.
4. After the calibration successfully completes, the Status is Pass.
To remove the disk drive from the instrument, do the following procedure:
1. Set the oscilloscope so that its bottom is down on the work surface and its
front panel is facing you. See Figure 1--1 on page 1--2.
CAUTION. Do not remove the replaceable hard disk drive when the instrument is
powered on. The replaceable hard disk drive may be permanently damaged if it
is removed while the instrument is powered on.
