Keysight MXR254A and MXR254B Infiniium Series Oscilloscopes
Comparison of Keysight MXR254A and MXR254B Oscilloscopes
Keysight MXR254A Infiniium MXR Series Oscilloscope
The MXR254A oscilloscope offers a bandwidth of 2.5 GHz on all four 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 and up to 8 channels. Standard features include InfiniiScan and Wave Gen.
Keysight MXR254B Infiniium MXR B-Series Oscilloscope
The MXR254B model has the same 2.5 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 MXR254A, 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.
