DCA 25021 Oscilloscope
The DCA25021 Optical Sampling Oscilloscope is designed for transmitter performance evaluation. It supports 4-channel optical signal inputs and is compatible with both NRZ and PAM4 signal testing. The optical channel bandwidth reaches up to 30 GHz, with multiple built-in standard filters, while the electrical channel bandwidth extends up to 35 GHz.
Equipped with a high-resolution, high-sampling-rate ADC, it enables continuous equivalent-time sampling technology. Combined with proprietary algorithms, it reconstructs eye diagrams with precision. The advanced circuit design ensures system noise remains below 3 μW. Paired with a calibrated reference receiver (compliant with industry tolerance standards), it perfectly meets the industry's need for accurate digital waveform testing.
Application
- Optical module eye diagram parameter test
- Optical Transmitter Performance Test
