The InfiniiVision HD3 Series from Keysight are Oscilloscopes that have a bandwidth of 200 MHz to 1 GHz. They have 2/4 analog & 16 digital input channels and a sample rate of up to 3.2 GS/s per channel with a vertical resolution of 14 bits. These oscilloscopes have deep memory with dedicated memory chips of 100 Mpts per channel and a waveform update rate of more than 1,300,000 waveforms per second. They have a rise time of less than 2 ns and noise density of less than -161.2 dBm/Hz. These oscilloscopes have a noise floor of 50 µV RMS, signal-to-noise dynamic range of 96 dB and a spurious free dynamic range (SFDR) of 79 dB.
The InfiniiVision HD3 Series oscilloscopes use Keysight’s HD3 architecture that includes a 14-bit ADC, 10 GB internal storage and a low-noise front end. The dedicated memory chips used in this architecture mean that there is no interleaving between channels, which enables users to get maximum memory and sample rate on every channel, even if all the channels are turned on. These oscilloscopes have a custom ASIC (MegaZoom 5) that enables them to have hardware-based functions such as zone trigger, serial decoding, and mask testing. They can be controlled manually via a 10.1-inch color display and remotely via USB 2.0/3.0 or LAN (10/100/1000Base-T) interfaces.
The InfiniiVision HD3 Series oscilloscopes require an AC supply of 100 to 120 or 240 V and consume less than 275 W of power. They are available in a benchtop module that measures 33.5 x 26.2 x 16.8 mm and has BNC connectors.
