The 5087A distribution amplifier provides the flexibility
required for distributing signals from the output of high-quality
frequency standards. Low distortion and excellent isolation make it
ideal for providing multiple outputs from atomic or crystal frequency
standards. The three input channels will accept 10 MHz or 5 MHz. The
number of outputs for each channel is selectable up to a total of
12. Voltage levels are individually adjustable from 0 Vrms to 3 Vrms
for each of the output channels.
Because the 5087A is modular, you can configure it for a variety of
distribution needs using special combinations of input and output
modules. Shielding around each input and output plug-in amplifier
ensures minimum noise and crosstalk. The tuned output amplifiers provide
clean signals and high channel-to channel isolation. A 115/230 VAC
power supply provides well-regulated current for the amplifiers. Line
voltage fluctuations have no measurable effect on the amplitude or
phase of the outputs. Provision for external 22-30 Vdc connections
ensures uninterrupted operation in the event of AC failure.
There are four normal configurations of input and output amplifiers. These are:
Option 031 - 3 Input Preamplifiers (100 kHz to 10 MHz) and 4 each 5 MHz, 1 MHz, and 100 kHz Output Amplifiers
Option 032 - 1 Input Preamplifier (100 kHz to 10 MHz) and 12 each 5 MHz Output Amplifiers
Option 033 - 1 Input Preamplifier (100 kHz to 10 MHz) and 12 each 10 MHz Output Amplifiers
Option 034 - 1 Input Preamplifier (100 kHz to 10 MHz), 1-5 MHz to 1 MHz Divider, 1-1 MHz to 100 kHz Divider and 4 each 5 Mhz, 1 MHz, and 100 kHz Output Amplifiers
