Introduction
The PTS50 was our first ever distribution amplifier and
hundreds have been sold since it was introduced in 1999.
The PTS50 takes a reference input and distributes it to
seven other outputs.
Reliability
With a massively high MTBF of nearly 1 million hours
(based on real data over the past 12 years) the PTS50 is
a very reliable unit.
Detailed Description
The PTS50 accepts a 5 or 10 MHz sinewave or squarewave
input and converts it to five 10 MHz sinewave outputs.
There are five sinewave, one squarewave and one slave
outputs.
Automatic Gain Control
A unique feature of our distribution amplifiers is the
fact that they have AGC (automatic gain control).
A variation in input level from -20 dBm to +20 dBm will
not cause the outputs to vary by more than 1 dB.
This is very useful in a large frequency distribution
system where long cable runs can cause different input
levels to the distribution amplifiers.
With the PTS50 output levels can be guaranteed.
Also, it has been shown that even ten PTS50's cascaded in
series still give a reliable output with no self
oscillation of excessive noise.
Outputs
There are five isolated sinewave outputs, one switchable
squarewave output and a rear panel slave output.
Each sinewave output is isolated from the other and from
the reference input. Any shorts are noise applied
to one channel will not affect another.
A useful feature of the PTS50 is that each output can be
independently set to any level from 0 dBm to > 13 dBm.
This is ideal where the PTS50 feeds different
manufacturers' of instruments, where each instrument has
a different input level requirement.
The squarewave output that can be switched
to 10 MHz, 5 MHz, 2 MHz, 1 MHz, 100 kHz and 1 pps (pulse
per second). This is useful for instruments that
use a different frequency input for their external
timebase.
The 1 pps is also useful in many applications.
A slave output enables more PTS50 to be cascaded in
larger systems.
Different Frequencies
Various models exist in the PTS50 range that operate at
different frequencies. Normally the output frequency is
exactly the same as the reference input frequency, but
frequency translation is also possible. For
example:
-
5 MHz input for a 10 MHz output
-
10 MHz input for a 5 MHz output
-
10 MHz input for a 15 MHz output
-
15 MHz input for a 10 MHz output
-
5 MHz input for a 1 MHz output
