STATEMENT OF WORK, detailed specification SRI isolation amplifier

NB687060-19-02215

Technical Requirements

The isolation amplifier shall comply with the following electrical specifications:

1. The amplifier shall have at least 8 independent channels

2. Each amplifier channel isolated output shall be able to supply at least +/- 15 mA of current to a load of 15 ohms at an input voltage less than +/- 1.5 V.

3. Each amplifier channel output shall be independently optically isolated from the input and each other. This includes all parts of the output circuit: signal, power, and ground.

a. The channel-to-channel leakage resistance shall be > 1 gigaohm

b. The channel-to-channel leakage capacitance shall be < 1 nanofarad

c. The channel-to-ground leakage resistance shall be > 1 gigaohm

d. The channel-to-ground leakage capacitance shall be < 1 nanofarad

4. Each amplifier channel shall have a bandwidth of DC to > 1 MHz

5. The amplifier will not use batteries.

6. The amplifier will be powered using a single standard IEC320 C14 male inlet, which is integrated into the unit and standard US wall power (120 V, 60 Hz).

7. The amplifier input shall use a single dsub-25 connector, with channel 1 signal/ground on pins

1/14 (respectively), channel 2 on pins 2/15, channel N on pins N/13+N

8. The amplifier output shall use a single dsub-25 connector, with isolated channel 1 signal/ground on pins 1/14 (respectively), isolated channel 2 on pins 2/15, isolated channel N on pins N/13+N

The digitizer shall comply with the following documentation specifications:

9. All manuals shall be provided electronically The digitizer shall comply with the following mechanical specifications:

10. The amplifier shall be rack-mountable and less than or equal to 2U in height The isolation amplifier shall comply with the following warranty specifications:

11. The amplifier shall have a 1-year warranty

The System shall be compatible with existing NIST SRI software/hardware.

Commercial Product Requirements

1. The isolation amplifier must be an established commercial product with at least one unit operating successfully in the field. Experimental or prototype items are not acceptable.

2. The isolation amplifier shall be a new (not refurbished or reconditioned) item covered by the original manufacturer’s full warranty. The use of “gray market” components not authorized for sale in the U.S. by the proposer is not acceptable.
