Keysight E1426A 4-Channel VXI Oscilloscope
The Keysight E1426A is a 500 MHz four-channel digitizing oscilloscope built as a 2-slot VXI module. It is a message-based VXI instrument designed for precision signal acquisition in automated test environments. The model delivers 8-bit vertical resolution and operates at a maximum sample rate of 20 MSa/s. The programmable attenuation provides vertical sensitivity from 8 mV to 40 V full scale across all channels.
The repetitive bandwidth of the E1426A oscilloscope spans from DC to 500 MHz across all four acquisition channels. For single-shot operation, bandwidth is DC to 2 MHz with simultaneous acquisition on channels 1 and 4. During repetitive measurements, data is acquired alternatively on channels 1 and 4, then on channels 2 and 3. Waveform record length reaches 1,024 points for repetitive mode and 500 points for single trigger sweep mode.
The vertical gain accuracy of the VXI Oscilloscope is ± 1.25% of full scale with vertical resolution rated at ± 0.4% for 8-bit A/D. With 10-bit averaging enabled, the vertical resolution of the model significantly improves to ± 0.1%. The input impedance is selectable between 1 MΩ and 50 Ω with a nominal input capacitance of 7 pF. The maximum input voltage is ± 250 V for 1 MΩ termination and 5 V rms for 50 Ω inputs.
The E1426A 4 Channel VXI Oscilloscope supports an offset range of up to ± 250 V across both input impedance configurations. The offset accuracy is specified as ± (0.5% of channel offset + 2% of the voltage range). The input coupling supports both AC and DC modes for versatile signal conditioning across test applications. The oscilloscope provides four storable setups and 64 KB of shared VXI RAM for segment storage.
The timebase range on the Keysight VXI oscilloscope spans continuously from 2 ns to 50 s full scale. The timebase resolution is 20 ps with a minimum trigger pulse width of 1.5 ns. The model employs random repetitive sampling, also known as equivalent time sampling, for high-frequency signal capture. A high-speed track-and-hold circuit captures the signal voltage before the lower-speed A/D converter digitizes it.
