General
Description
The DA101010 is a 10 MHz distribution
amplifier. It can be used for synchronizing up to
13 instruments to a
common frequency reference. Typically, the
reference will be 10 MHz signal from a primary
frequency oscillator (other input frequencies are
available). The reference output frequency will be
exactly the same as the input frequency.
A unique
feature of the DA101010 is automatic gain control (AGC).
AGC allows the input level to vary from -10 dBm to +20
dBm without the output levels changing. Inputs as
low as -30 dBm still produce a valid output signal.
Sinewave Outputs
There are
ten sinewave outputs. Harmonics are typically 70
dB down on the carrier (-70 dBc), ideal if the 10 MHz
outputs are used in a multiplier situation.
Every
output can be independently set to an level,
anywhere from 0 dBm to over 13 dBm. This is useful
where instruments with different reference input levels
are to be connected to the DA101010.
Squarewave Outputs
Two
squarewave outputs drive TTL squarewave signals into an
open circuit or 50 ohm impedance. The frequency of
each squarewave output can be independently set to 10
MHz, 5 MHz, 2 MHz, 1 MHz, 100 kHz or 1 pps (pulse per
second). Frequency control is by two front panel
rotary switches.
This is
useful if the equipment to be synchronized uses a
different frequency to 10 MHz.
Slave Output
A slave
output is also available to connect further distribution
amplifiers. In this way over 1000 outputs can be
derived from one signal frequency reference.
Applications
The DA101010 10 MHz Distribution Amplifier is ideal for
use in calibration or standard laboratories, radio
repair workshops or production facilities.
Many Options Available
There are many options available for the DA101010
series. If your requirement doesn't exist, we'll
make it especially for you.
Options include:
-
Different frequencies. Any frequency from 1
MHz to 15 MHz is available in the DA101010 series.
Frequencies from < 1 Hz to over 1 GHz are available
with other models manufactured by us.
-
Redundancy, whereby two units operate as a pair.
If one unit should fail, the second unit takes over.
-
Sinewave or squarewave outputs.
-
Internal back-up oscillator, automatically switched
in if the external signal fails.
-
Multiplied or divided outputs. E.g. 5 MHz
input, 10 MHz output.
-
High output levels, up to +20 dBm.
-
Different gain versions, so input levels from -50
dBm to +20 dBm can be tolerated.
-
External DC back-up power input. Automatic
switchover from AC to DC.
