SECTION III OPTIONAL EQUIPMENT
3-1
Available Options
Listed below are the options available for use with the Model 4300B and 4350ATE Digital Micro-ohmmeters.
Option RX-3: Rack Ears
Option "RX-3" is a set of rack ears that permit
mounting of the instrument in a standard 19"
equipment rack.
Option TL-488: IEEE Interface
Option "TL-488" is an IEEE-488 GPIB Talk-
Listen interface that allows control via the IEEE-
488 Bus for remote range programming and
resistance measurement data acquisition. See
Section 5.
Options GP-1, GP-2: GPIB Cable
1
or
2
meter IEEE-488 GPIB interface cable for
use with Option TL-488.
Option BCD: Data Outputs
Option "BCD" is a parallel binary-coded-decimal
data interface with outputs for display and range
data. See Section 6.
Model 1248: Dual-Limit Comparator
The Valhalla Model 1248 may be used in
conjunction with a Model 4300B and Option BCD
above. The Model 1248 is a dual-limit
comparator that interprets the display indications
of the 4300B as either "HI", "LO" or "GO", based
on a window that is set by the user. Relay contact
closure is provided to trigger an alarm, batch
sorter, counter or other device. The mating cable
from the 4300B to the 1248 is 2½ feet in length
and designated as "IDC-3".
Option IDC-3: BCD Interface Cable
Option IDC-3 is an interface cable designed
specifically to connect the 4300B BCD output to
the inputs of the Model 1248 BCD Comparator.
It is 2½ feet in length and is terminated on one
end in a 50 pin Amphenol connector with wire
break-outs, and on the other end in a 24 pin
Amphenol connector that mates with the BCD
output port of the 4300B. See drawing number
4300-051 at the back of this manual.
Options RS232 and PAR: Interfaces
The ohmmeter is now available with optional
serial and/or printer interfaces. The serial
interface is designed to be compatible with
RS232C systems. This interface may be used for
remote data acquisition only, and does not allow
mode or range control. The printer interface is
compatible with Centronics parallel printers, and
may be configured to print raw data or labels.
If either of these options has been installed, please
refer to Section 10 for operating instructions.
Options AL and CU: Compensators
Option "AL" is a compensating temperature
sensor for aluminum (4030 ppm/
°
C) providing a
20
°
C or 25
°
C reference.
Option "CU" is a compensating temperature
sensor for copper (3931 ppm/
°
C) providing a
20
°
C or 25
°
C reference.
Option CK: Extension Cable
Option "CK" is a 4' shielded extender cable that
permits the placement of compensators in closer
proximity to the resistor under test.
