The CD drive is a slim-line CD-RW drive. The actual C D-RW drives may vary
as new drives become available.
A dual external USB 2.0 port allows external connection to USB devices. Two
ports are use internally by the keypad and the floppy disk drive.
Software
The instrument operation is controlled by the TLA Application Software built
upon the Windows Operating System.
Probe Interface
The logic analyzer connects to the target system through the probe interface. The
logic analyzer can use the following probes to acquire data from the target
system:
H P6417
H P6418
H P6419
H P6434
Depending on the instrument configuration, you can connect up to eight P6417,
P6418, and P6419 general purpose probes or up to four P 6434 high-density
probes.
Acquisition
The acquisition board is mounted on the bottom of the instrument. The number
of channels for each logic analyzer depend on the configuration. The acquisition
board takes the data from the probes, determines when to clock the data into
memory, and communicates the acquisition information with the rest of the
instrument.
Depending on the instrument configuration the logic analyzer has zero, one, or
two daughter boards that provide for additional probe connections.
No manual adjustments or calibration exist. All calibration is done by software
but requires the TLACAL1 fixture for the adjustment procedures. The adjust-
ment procedures are described in the Adjustment Procedures chapter of this
manual.
