NIST Requirements Document Arbitrary Waveform Generator (AWG)

I. Background/ Scope This acquisition is requested in support of the project “Atom-Based Metrology” in Atom-scale device group (Nanoscale Device Characterization division) who are currently capable of fabricating Phosphorus donor-based quantum devices (single electron and single atom transistors) at the atomically precise scale in silicon using hydrogen resist based STM lithography. This acquisition is to produce the ability to demonstrate a coherent spin manipulation in quantum device consists of a single donor atom tunnel coupled to a single electron transistor island in a parallel configuration at cryogenic temperatures. For this requirement, the project needs an “Arbitrary Waveform Generator” for (i) creating a pulse sequence required for performing single-shot spin readout experiments (ii) sending I and Q differential signals to E8267 microwave generator for performing coherent manipulation on spin qubit.

II. Minimum Requirements The system shall meet or exceed the minimum requirements identified below. 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.

The Contractor shall provide one (1) arbitrary waveform generator (AWG) brand name Tektronix AWG5204 that meet the following salient characteristics:

1) The AWG must be a self-contained unit.

2) Must have a front panel with controls and a display which is required to generate/synthesize signals.

3) The AWG must not require a computer in order to provide a voltage or arbitrary waveform. However, it is allowable for a computer to be required for downloading arbitrary waveforms to the AWG.

4) Shall have a minimum of four (4) independent channels.

5) Speed:

a. sample rate of at least 10 GSa/s (on all four channels)

b. the bandwidth (effective frequency output) of at least 2 GHz,

c. rise time less than 150 ps defined by at least 750 mVpp.

6) AWG shall havedigital synthesized baseband generation, intermediate frequency (IF)/ Radio frequency (RF) signal modulation as a required functionality. The unit shall have built in I/Q modulator operating over bandwidth of AWG.

7) AWG shall have sequencer for running arbitrary signals in continuous, triggered or gated mode.

8) Synchronization of channels: Channel to Channel skew must be less than 40 ps.

9) Output amplitude: peak-to-peak amplitude of at least 0.4 V.

10) Must be capable of being rackmounted.

11) Memory: a minimum of 2 giga bit samples per channle.Digital to analog converter (DAC) characteristics:

a. Shall be of at least 16 bit without markers.

b. Shall have at least two markers per channel.

c. Effective number of bits at 4 GHz of bandwidth should be a minimum of 7-bits.

12) Playtime of AWG:

a. With sample rate equal or greater than 10 GSa/S and memory of equal or greater than 2 GSa/channel

b. Shall allow continuous playtime greater than 300 ms.

13) Duration of arbitrary signal: In addition to the requirement for total memory, the AWG must be able to switch between different waveforms, to yield a total signal duration longer than the total memory. For instance, we must be able to set up the AWG so that it switches between two different arbitrary waveforms for a total duration of at least 1 second. This ability is often called “sequencing” by OEM’s

14) Distortion: Vertical and horizontal faithfulness. The signal produced by the AWG must be faithful to the arbitrary waveform within 20% for both vertical voltage and horizontal time specifications (excluding effects due to rise/falltime). For instance, the amount of overshoot after an abrupt pulse must be no greater than 20% of the full-scale signal.

15) Spurious Free Dynamic Range: At 10 Gsa/S, with analog channel output frequency of 100 MHz, the in band performance measured across 0.01 to 1 GHz shall be at least -70 dBc

16) Instrument control: GIPB/Ethernet/RS-232 interfacing option for interfacing unit via LabVIEW or python

17) Manuals: User manual must be printed as well as electronic (note to OAAM: This specification for manuals must be part of specifications – do not move to separate line item)

III. Delivery Delivery shall be FOB Destination (or equivalent terms, such as INCOTERMS Delivered Duties Paid) are required and shall occur not later than (NLT) ten (10) weeks after receipt of an order (ARO).

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. The contractor shall deliver all Line Items to:

The National Institute of Standards and Technology 100 Bureau Drive, Building 220 Gaithersburg, MD 20899-1640 IV. Inspection and 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. The inspection/measurement of following characteristics shall be completed:

1. Test that the instrument can make arbitrary waveforms as per data sheet using a signal analyzer or oscilloscope with specs allowing testing of required performance specs.

2. Test that the instrument can deliver I and Q differential signals using a signal analyzer or oscilloscope with specs allowing testing of required performance specs.

3. Ensure the instrument can interface with Labrotary computer via LabVIEW or python

The Government will test, inspect, and accept the equipment onsite within fourteen (14) business days of the receipt of the AWG. A visual inspection of the AWG will be performed by the NIST TPOC to identify surface defects or any form of indication that the AWG was 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 the AWG due to defects and/or nonconformance.

Not required.

V. Warranty The contractor shall warrant the entire system for a period of a minimum of three (3) years after receipt of the equipment and shall be in accordance with terms in FAR 52.212-4

VI. Payment Schedule The Contractor shall be paid, in accordance with Net 30-day payment terms, upon receipt and acceptance of a proper invoice, in accordance with the following schedule:

1. 100% after installation and acceptance by the TPOC of fully installed system.

2. The Government anticipates inspection will occur upon:

a. After the testing procedures set forth in this document have been completed
