END OF SECTION 3

SECTION 4: BASIS OF AWARD

A. Basis of Award – Lowest Price Technically Acceptable (LPTA) The Government will award a firm fixed price purchase order resulting from this solicitation once the Contractor is verified as responsible and the quotation conforming to the solicitation is found to be the lowest price technically acceptable offer.

B. Evaluation Criteria The Government intends to award a single purchase order from this RFQ to the responsible offeror whose quotation, conforming to the solicitation, is the lowest price, technically acceptable quotation. The Government reserves the right not to award a purchase order.

Technically acceptable means that the offeror provides the equipment/services as specified in the Statement of Work. No prototypes or demonstration models will be considered. Evaluation of technical capability shall be based on the information provided in the quotation. The National Institute of Standards and Technology (NIST) will evaluate whether the offeror has demonstrated that its proposed equipment/supplies meet all minimum requirements. If an offeror does not demonstrate how the equipment/services meet the required technical specifications NIST will determine the offer is not technically acceptable.

The proposed pricing will be evaluated to determine that the total price is consistent with the technical portion of the quotation and is a fair and reasonable overall price to the Government.

NIST intends to evaluate quotations and issue a purchase order based on the initial quotes received. Therefore, the offerors initial quote should contain the offerors best terms from a price and technical standpoint. NIST reserves the right to request revised quotes from, or negotiate final contract terms with, one or more, but not all, Contractors if later determined by the Contracting Officer to be necessary.

SECTION 5: STATEMENT OF WORK

NIST Statement of Work Title: DAQ with 24-bit digitizer for lock-in amplifier replacement Requesting Lab: National Institute of Standards & Technology (NIST) Physical Measurements Lab (PML) Temperature and Humidity Group

BACKGROUND

NIST requires a quantity of three (3) DAQs with (4) 24-bit digitizer modules to construct equivalent lock-in amplifiers (LIA) for improving resolution of periodic signals generated from optical measurements. All traditional dedicated LIAs available on the market have at most 16 bits of digitization and up to a 1 V range, leading to resolution issues when acquiring measurements from optical systems with small signal responses. In other words, traditional LIAs will show a stable signal with zero variation, when the signal is indeed changing at a level the LIA cannot discern due to the resolution of the LIA digitizer. Constructing an equivalent LIA using a DAQ and a high-resolution digitizer will overcome this issue while simultaneously enable a greater range of signal magnitudes to be measured. By constructing a LIA using these high-resolution digitizers, smaller changes in optical signals can be detected due to the increased resolution, allowing for more sensitive measurement.

SCOPE

The contractor shall deliver a quantity of three (3) DAQ units Keysight model number DAQ970A, and a quantity of four (4) 24-bit digitizer modules, Keysight model number DAQM909A, inclusive of FOB Destination delivery terms (or equivalent INCOTERMS), and warranty.

MINIMUM REQUIREMENTS

Offeror shall submit a firm fixed price quotation for all items. The offered supplies shall be the exact model stated in this document. All items must be new. Used or remanufactured equipment will not be considered for award. Experimental, prototype, or custom items will not be considered. The use of “gray market” components not authorized for sale in the U.S. by the Contractor is not acceptable. All line items shall be shipped in the original manufacturer’s packaging and include all original documentation and software, when applicable.

BRAND NAME JUSTIFICATION

NIST requires a quantity of three (3) DAQs with four (4) 24-bit digitizer modules to construct equivalent lock-in amplifiers (LIA) for improving resolution of periodic signals generated from optical measurements. All traditional dedicated LIAs available on the market have at most 16 bits of digitization and up to a 1 V range, leading to resolution issues when acquiring measurements from optical systems with small signal responses. In other words, traditional LIAs will show a stable signal with zero variation, when the signal is indeed changing at a level the LIA cannot discern due to the resolution of the LIA digitizer. Constructing an equivalent LIA using a DAQ and a high-resolution digitizer will overcome this issue while simultaneously enable a greater range of signal magnitudes to be measured. By constructing a LIA using these high-resolution digitizers, smaller changes in optical signals can be detected due to the increased resolution, allowing for more sensitive measurement.

The required DAQs with modules must meet the salient characteristics identified below. The specification are not able to be scaled back and remain technically acceptable for this application.

Technical requirements:

1. 24-bit digitization

2. At least 800,000 samples/s

3. Can digitize signals 1 uV to 20 V

4. Instrument can be interfaced without 3rd party software (e.g. ASCII commands)

Market research findings discovered the only technically acceptable DAQs with modules is the Keysight Technologies model DAQ970A and Keysight technologies model DAQM909A for the modules. The models are not available on GSA and Keysight has at least six (6) resellers for these models.

Line Item 0001 Description: DAQ Units, Keysight Technologies model number DAQ970A Quantity: Three (3)

Line Item 0002 Description: 24-Bit- Digitizer Modules, Keysight Technologies model number DAQM909A Quantity: Four (4)

DELIVERABLES

DELIVERY

Delivery shall be FOB Destination (or equivalent terms, such as INCOTERMS Delivered Duties Paid). FOB Destination means: The contractor shall pack and mark the shipment in conformance with carrier requirements, deliver the shipment in good order and condition to the point of delivery specified in the purchase order, be responsible for any loss of and/or damage to the goods occurring before receipt and acceptance of the shipment by the consignee at the delivery point specified in the purchase order; and pay all charges to the specified point of delivery.

INSPECTION & ACCEPTANCE

In addition to the inspection and acceptance terms articulated in 52.212-4, the Government reserves the right to perform such performance tests and evaluations as defined below to verify specified system performance. Such tests and evaluations, if performed, shall be conducted within the environment that the system is to be operated. The Contractor has the right to be present during the tests and evaluations, if performed, at the Contractor’s expense.

Performance Tests

1. DAQ unit digitizes sample signals from function generator.

2. Digitizer is repeatable, linear. Digitized signals able to be reliably compensated, if necessary.

a. Calibrate the DAQ/digitizer combination against a voltage source

b. Generate a compensation for each unit from this calibration

3. DAQ can be interfaced with USB using Python 3

The Government will test, inspect, and accept the equipment onsite within 7 business days of the receipt of the supplies. A visual inspection of the supplies will be performed by the NIST TPOC to identify surface defects or any form of indication that the supplies were damaged during transport to NIST. The Government shall have sole discretion to require repair or replacement of damaged and/or nonconforming supplies at no cost to the Government. The Government at any time prior to acceptance shall reject supplies due to defects and/or nonconformance.

WARRANTY
