Hardware Resolution and HD4096 Technology
Teledyne LeCroy offers oscilloscopes with either traditional 8-bit vertical resolution or 12-bit high-definition hardware. Scopes like the WaveRunner 640Zi, WaveSurfer 104MXs-A, WaveRunner 44Xi-A, and WavePro 735Zi-A utilize 8-bit analog-to-digital converters, which can achieve up to 11 bits of vertical resolution using Enhanced Resolution (ERES) software.
For applications requiring higher precision, models such as the HDO4104, HDO6104, and HDO8108 employ HD4096 technology with a true 12-bit ADC. This hardware architecture delivers sixteen times more resolution than standard 8-bit systems. With ERES, these high-definition models can achieve an enhanced vertical resolution of up to 15 bits, facilitating the observation of clean and highly detailed signal features.
Bandwidth and Sampling Across Product Families
Instrument selection depends heavily on target signal speeds. Entry-level and mid-range benchtop requirements are addressed by instruments such as the benchtop digital storage oscilloscope WaveSurfer 10, the LT224 (200 MHz with color CRT), WAVESURFER 3024 (200 MHz), WaveSurfer 44MXs-A (400 MHz), WaveSurfer 3054 (500 MHz), and WAVESURFER 64MXS (600 MHz).
For higher frequencies, the WaveRunner series, including the 2 GHz WaveRunner 204MXi-A and the 4 GHz WaveRunner 640Zi, provides sampling rates up to 40 GS/s interleaved. High-speed, long-memory performance is available via the WavePro series, with models like the WavePro 725Zi-A (2.5 GHz), WavePro 7300A (3 GHz), and WavePro 735Zi-A (3.5 GHz) supporting up to 200 GS/s Random Interleaved Sampling (RIS) for repetitive signals.
Serial Data Analysis and System Expansion
The Serial Data Analyzer (SDA) series, which includes the SDA 6000A, SDA 760Zi, and the 11 GHz SDA 11000, is tailored for physical layer testing, compliance verification, and jitter analysis. These analyzers feature specialized capabilities, including eye diagram analysis. The SDA 11000 provides two active channels at its full 11 GHz bandwidth.
System capabilities can be expanded using dedicated modules and probes. The MS-500 mixed-signal module adds 36 digital channels to compatible host platforms, featuring an input impedance of 100 kΩ and a maximum input frequency of 250 MHz. For current measurements, the CP150 current probe integrates via the ProBus interface to offer AC/DC current measurements up to 150 A rms (300 A peak) with a DC to 10 MHz bandwidth.
Frequently asked questions
- What is the difference between ProBus and ProLink interfaces?
- ProBus is used for standard active and passive probes, including current probes like the CP150. ProLink is designed for high-bandwidth inputs, such as those found on high-speed serial analyzers like the SDA 11000.
- Can 8-bit Teledyne LeCroy oscilloscopes perform high-resolution measurements?
- Yes, 8-bit models like the WaveRunner 44Xi-A and WaveRunner 640Zi feature an Enhanced Resolution (ERES) mode, which uses software filtering to increase vertical resolution up to 11 bits.
- How many digital channels does the MS-500 MSO module add?
- The MS-500 adds 36 digital channels to compatible host oscilloscopes, with a maximum sampling rate of 2 GS/s on 18 channels or 1 GS/s on 36 channels.
