Functional Description:

The function of a Distribution Amplifier is to create multiple copies of a signal while minimally degrading its integrity.  The DA100-2 model Distribution Amplifier is designed to distribute a low noise 10 MHz frequency reference signal to multiple usage points, such as Automated Test Systems or Test Benches where equipment requiring a 10MHz reference may be employed.

The amplifier has one input and five outputs.  The device may be configured with either SMA or BNC connectors (see Options Section for more information). The input is AC coupled and offers an input source impedance of 50 Ω at 10 MHz.

The input is conditioned by a limiter circuit, which provides a fixed output level as well as high input gain.  The high input gain allows the amplifier to provide the specified output power over the entire input power range.  It also makes the amplifier tolerant of essentially any waveform with a duty cycle near 50%.

The input limiter is followed by three amplifier/low pass filter stages, which insure low distortion sine wave outputs.  The outputs from the filter stages are supplied to fixed gain output amplifiers as illustrated in the block diagram below.  This configuration minimizes channel to channel phase offsets (<1 nS); the phase offset from the input to any output is less than 5 nS at 10 MHz.

Multiple amplifiers may be ‘daisy chained’ together by connecting the output of channel five to the input of another DA100-2 device.  However, this configuration increases phase errors between amplifiers.  If channel to channel phase error is a concern, a better solution is to use a single amplifier to drive up to five additional amplifiers, thus providing up to 25 outputs with optimal channel to channel phase degradation.

Notes:
1 - Input signal waveform can be any type with a 50% duty cycle
2 - The device may be powered with a user-supplied voltage via the screw
     terminal connections or by the 2.1 mm plug on the included 6 V, 500 mA
     power module.  When the power module is utilized, the module voltage is 
     made available on the screw terminals thus allowing the user to access 
     6 V, 250 mA to power external circuitry.
     Caution:  Do not connect an external supply voltage to tbe screw terminals 
                      when using the power module.

Warranty:

Device comes standard with a one year manufacturers warranty.  Faulty devices will be repaired or replaced if they are defective due to a manufacturing defect.  Misuse or operation outside of the stated limits above will void warranty.  Damage caused by such misuse or operation outside of specified limits will not be covered under warranty.

Calibration Service Option: 

Includes verification that device meets all manufacturer specifications.  If device has adjustments, the device's performance is optimized.  If the device is not operating within specified limits and can not be adjusted to do so, the customer is notified, and a cost estimate to repair the device will be issued.  If the device is under warranty and the non-compliance to manufacturer specifications is due to a fault covered under warranty the device will be repaired or replaced.  One, three, and five year plans are available for purchase.

Extended Warranty Option:

Extended warranty option provides an additional two years of manufacturers warranty.  Faulty devices will be repaired or replaced if they are defective due to a manufacturing defect.  Misuse or operation outside of the stated limits above will void warranty.  Damage caused by such misuse or operation outside of specified limits will not be covered under warranty.
