What is the TDS7000 and how does it compare to the CSA8000?
The CSA 7000-series are real-time oscilloscopes. They have very high sample rates (up to 20Gs/s) and up to 4Ghz BW. These products also have an optical input for acquiring optical signals up to 3.125Gb/s (on the CSA 7404B). These products also have four electrical inputs. This makes these products very versatile.
The 8000-series is very different. The 8000-series are sampling oscilloscopes, which have compartments to accommodate both optical sampling modules as well as electrical sampling modules. Therefore, like the CSA7000 series, the 8000-series can acquire both optical and electrical signals.
However, both are excellent products for acquiring optical and electrical Telecom and Datacom signals and performing mask testing as well as make a wide array of measurements.
The key differences between the product families are:
- The CSA 7000-series acquires data real-time. The 8000-series are sampling oscilloscopes. For every trigger, one sample is acquired. Therefore, the 8000-series needs a repetitive signal to build a waveform.
- The maximum BW for the CSA 7000-series is 4Ghz. The BW of the modules being used limits the 8000-series BW. BW of over 60Ghz is available in both electrical and optical modules.
- The CSA 7000-series has options for very long record lengths. The 8000-series has a max record length of 4000 samples.
