Functional Overview

This chapter provides the overview of the features provided by the HDAWG Instrument. The first section contains the description of the graphical overview and the hardware and software feature list. The next section details the front panel and the back panel of the measurement instrument. The following section provides product selection and ordering support.

Features

The HDAWG Instrument according to Figure 1 consists of several internal units (light blue color) surrounded by several interface units (dark blue color), the front panel on the left-hand side and the back panel on the right-hand side. The arrows between the panels and the interface units indicates selected physical connections and the data flow. The orange blocks are optional units that can be either ordered at the beginning or upgraded later. The HDAWG Arbitrary Waveform Generator comes in two model variants, the HDAWG4 (4 channels) and the HDAWG8 (8 channels). Ordering Guide details the available upgrade options for each instrument type and whether the corresponding option can be upgraded directly in the field. The arbitrary waveform generator output is generated on 4 or 8 Wave signal outputs.

The numerical oscillators generate sinusoid signals that are used for digital modulation of the AWG signal. Hardware trigger signals are used for timing synchronization within the instrument and with external equipment, such as digitizers, or pattern generators.

When using the HDAWG and the UHFQA in a Zurich Instruments Quantum Computing Control System, the two instruments need to be connected with a VHDCI cable between their respective DIO ports. Due to the different voltage levels of the DIO connectors on the HDAWG and UHFQA, a passive voltage level shifter needs to be placed in series with the VHDCI connection. It is furthermore recommended to use a mechanical stabilization of the VHDCI connection on the HDAWG side in order to prevent damage to the DIO connector due to cable pull. A set of a VHDCI cable, a level shifter, and a mechanical stabilization part are available as DIO Link Set from Zurich Instruments upon request under [email protected].

The DIO Link Set is shown in Figure 5.

Please follow the instructions below in order to install the DIO Link Set between the HDAWG and the UHFQA.

  1. Fix the DIO level shift fixture anchor to the DIO connector on the UHFQA using the screws already installed on the UHFQA DIO port.

  2. Fix the DIO level shifter fixture to the anchor using the two M3*10 mm screws.

  3. Clamp the DIO fixture (slider and body) lightly to one of the connectors of the VHDCI cable using the two M4*10 mm screws. This side of the cable is to be connected to the HDAWG.

  4. Connect the VHDCI cable between the DIO level shifter fixture and the DIO port on the HDAWG and tighten the manual screws on both VHDCI connectors.

  5. Push the DIO fixture (slider and body) firmly towards the HDAWG casing and tighten the two M4*10 mm screws to increase the mechanical stability of the VHDCI cable connection.
