Comparison of Keysight MXR208A and MXR208B Oscilloscopes

Keysight MXR208A Infiniium MXR Series Oscilloscope

The MXR208A oscilloscope offers a bandwidth of 2 GHz on all eight channels with a sampling rate of 16 GSa/s. It integrates eight instruments into one device:

• Oscilloscope
• Logic analyzer
• Protocol analyzer
• Digital voltmeter
• Frequency counter
• Real-time spectrum analyzer
• Frequency response analyzer
• Signal generator

The device is equipped with a 10-bit ADC with an effective number of bits (ENOB) up to 9.0 and a noise level as low as 43 μV. The maximum memory depth is 1.6 Gpts. The model is fully upgradeable, including bandwidth expansion up to 6 GHz. Standard features include InfiniiScan and Wave Gen.

Keysight MXR208B Infiniium MXR B-Series Oscilloscope

The MXR208B model has the same 2 GHz bandwidth and similar specifications but offers significant performance enhancements:

• Up to 70% faster jitter analysis
• Up to 65% faster power integrity analysis
• Up to 45% faster FFT execution
• Up to 15% faster USB 2.0 compliance testing

Like the MXR208A, this model includes a 10-bit ADC with ENOB up to 9.0 and a noise level of 43 μV, and it is fully upgradeable.
