1693 RLC Digibridge
In the above example, the remote message codes:
MLA and MTA are X0100011 and X1000011, respec-
tively. Thus, the listen address and the talk address are
distinguished, although they contain the same set of
device-dependent bits, which you set into S2.
Data Output: Data (results of measurements) are
provided on the D10l...D107 lines as serial strings
of characters. Each character is a byte, coded ac-
cording to the 7-bit ASCII code, as explained above.
The alphanumeric characters used are appropriate to
the data, for convenience in reading printouts. The
character strings are always provided in the same
sequence as that tabulated in paragraph 3.11.13; for
example: RLC value, QDR value, bin number - if all
3 were selected (by the X7 command). The carriage-
return and line-feed characters at the end of each
string provide a printer (for example) with the basic
commands to print each string on a separate line.
For example, if the measurement was 0.54321 μF
(1 kHz, range 4 held), the character string for RLC
U(space)C(space)μF(2 spaces)0.54321(CR)(LF)
value is:
If the D measurement was .001, the character string
(2 spaces)D(5 spaces)00.00l0(CR)(LF)
for QDR value is:
If the measurement falls into bin 9, the character string
F(space)BIN(2 spaces)9(CR)(LF)
for bin number is:
The character string for RLC value has the length of
17 characters; for QDR value, 17 characters; for bin
number, 10 characters - including spaces, carriage-
return, and line-feed characters. Refer to the format
tables in Section 3.11.12 for details.

2.8 Environment

The Digibridge can be operated in nearly any environ-
ment that is comfortable for the operator. Keep the
instrument and all connections to the parts under test
away from electromagnetic fields that may interfere
with measurements.
Position the instrument with consideration for ample
air flow to the side and rear ventilation holes. The
recommended space around the instrument is at least
3" (75 mm). The surrounding environment should be
free from excessive dust to prevent contamination of
electric circuits.
Refer to the Specifications at the front of this manual
for temperature and humidity tolerances. To safeguard
the instrument during storage or shipment, use protec-
tive packaging. Service personnel refer to Section 5.
When the Digibridge is mounted in a rack or other
enclosed location, make sure that the ambient tem-
perature inside the rack does not exceed the limits
specified under ''Environment'' in the Specifications
at the front of this manual, and that air can circulate
freely past all air inlet and outlet vents.

2.9 Rack Mount Option

To rack mount the unit, place the instrument on the
shelf (1689-9611) so that its feet drop through the
large holes.
Then position this assembly in the rack as desired
and secure with four 10-32 screws. If the rack does
not have threaded holes, use the supplied clip nuts.
