FIREBERD 6000 MAINFRAME SET-UP
Perform this procedure to configure the FIREBERD
6000 with the RS-449/530/MIL Interface.
(1) Turn the AC power ON. If necessary, release the
SELF LOOP pushbutton before starting.
(2) Set the DATA switch to the appropriate test pattern.
Refer to the FIREBERD 6000 Reference Manual for
descriptions of the test patterns.
(3) Set the GEN CLK switch to the appropriate genera-
tor clock source:
SYNTH -
If the synthesizer is selected, use the
MENU switch to select the SYNTH FREQ (synthe-
sizer frequency) menu. Select the desired frequency
from the softkeys or enter it through the keypad from
50 k b/s to 15 Mb/s.
INTF -
Provides the generator clock through the
interface received clock in synchronous mode and in
recovered clock mode.
BNC -
Allows an input from an external clock source.
The external clock source is input through the GEN
CLK IN connector on the rear panel.
(4) Set the TIMING MODE switch to the appropriate
timing mode as required:
SYNC -
Selects the synchronous timing mode. With
synchronous timing, operation to 15 Mb/s is pos-
sible. The default is SYNC.
ASYNC -
Select the asynchronous timing mode.
Asynchronous timing is limited to data rates up to 20
kb/s. The following PATTERNs are valid in asyn-
chronous testing: MARK, SPACE, 1:1, 63, 511,
2047, 215-1, FOX, and USER 1-3. When using
asynchronous timing, set the MENU switch to the
CHAR FORMAT menu to select DATA BITS,
PARITY, and STOP BITS.
RECOVD -
Selects the recovered timing mode.
(5) If the AUX FUNC IN USE indicator is illuminated
scroll through the Auxiliary Function IN USE list to
identify auxiliary functions that might affect the
operation of the RS-449/530/MIL Interface.
(6) Select the desired ANALYSIS MODE: CONTINU-
OUS or SINGLE.
(7) Select the applicable categories and results displays
from the ANALYSIS RESULTS panel.

FIREBERD 6000 INTERFACE SET-UP
This section describes how to access the interface menu
and discusses each of the menu selections in the RS-449/530/
MIL Data Interface menu.
The RS-449/530/MIL Data Interface is controlled through
the FIREBERD 6000 INTERFACE SETUP category. Press
the MIL449 softkey to access the MIL449 interface menu.
Press the appropriate softkey to select a function or another
menu. To return to the previous menu display press the
mainframe keypad “up arrow” key. To return to the main
interface menu, press the mainframe ENTER key. Press the
softkeys to select a function as indicated by the softkey labels
on the bottom line of the display. All interface menu settings
are retained when power is removed from the mainframe. See
Figures 5-2 through 5-5 for the interface menus.
5.4.1
Operating Type Menu
The Operating Type (TYPE) menu allows the user to
select either MIL188114, RS449, EIA530, or MIL188C as the
type of interface operation. Press the appropriate softkey to
select the desired operating type. Press the MORE key to
display the 188C softkey label. Modifying TYPE will cause
a test restart.
188114 -
The 188114 operating type configures the
interface to be connected to a MIL188-114 compatible
circuit.
RS449 -
The RS449 operating type configures the inter-
face to be connected to a RS-449 compatible circuit.
EIA530 -
The EIA530 operating type configures the
interface to be connected to a EIA-530 compatible
circuit.
188C -
The 188C operating type configures the interface
to be connected to a MIL188C compatible circuit.
