OUTPUTS: There are up to nine DDS8p synthesizers internal to the 1450A/02-AH. The output
frequency range of each is 10kHz to 120MHz, ACMOS, in 1
µ
Hz steps per LSB on the parallel
interface. Outputs are SMA female on rear panel, 50
Ω.
See below for operating modes.
INPUT: External Clock, 10MHz
±
5ppm, >1Vrms, 50
Ω.
Circuitry detects, locks to and tracks this
input when present. An internal TCXO (10MHz
±
2ppm) is used if the 10MHz external clock input is
left unconnected. SMA Female.
PHASE and FREQUENCY CONTROL: The Parallel interface is on a 90-pin EDAC 516-series
connector receptacle on the rear panel. An adapter board for use with ribbon cables is available. See
below for connector details.
SIZE: 19inch 2U rackmount case with mounting ears, 16inches deep, not including connectors.

ENVIRONMENTAL: Intended for laboratory/central office environment of: +5
o
C to +40
o
C with
humidity 80% to 31
o
C, decreasing linearly to 50% at 40
o
C.
OPERATION: Illuminated front panel power switch. Rear panel mode select switch. Front panel
“IN LOCK” and “POWER OK” LEDs.
