Digital Oscilloscope (4 GHz / 4 Channel)
Whether you have to debug your latest design or verify compliance, it is critical that your oscilloscope displays a true representation of your signal. This requires world-class signal integrity. Infiniium S-Series oscilloscopes were designed with this in mind. The S-Series provides a superior time base, front-end, and ADC technology blocks. This gives you a platform with up to 16 bits of resolution, low noise, low jitter, and a high effective number of bits (ENOB) - giving you visibility into the true performance of your device.
Several versions available
The Keysight Infiniium S series comes with four analog channels and is available with mixed-signal capability, as well as bandwidth ranging from 500 MHz to 8 GHz. Please note, that it is possible to add the MSO function post-purchase.
The chart below provides a brief overview of each. 6 GHz and 8 GHz are only possible when two channels are active. Four-channel bandwidth is 4 GHz.
| DSO model | MSO model | Analog bandwidth |
| DSOS054A | MSOS054A | 500 MHz |
| DSOS104A | MSOS104A | 1 GHz |
| DSOS204A | MSOS204A | 2 GHz |
| DSOS254A | MSOS254A | 2.5 GHz |
| DSOS404A | MSOS404A | 4 GHz |
| DSOS604A | MSOS604A | 6 GHz |
| DSOS804A | MSOS804A | 8 GHz |
Superior low-noise front end
A high-resolution ADC’s usefulness is dependent on the low-noise front end that supports the additional quantization levels. Each S-Series oscilloscope incorporates the industry’s lowest noise front end for portable oscilloscopes with bandwidth up to 8 GHz. The S-Series frontend includes three custom ICs, including a 130 nm BiCMOS IC that incorporates user-selectable analog filters and bandwidth upgrades via a software license.
