Oscilloscope Specifications
The dual-channel oscilloscope features 50MHz bandwidth on both CH1 and CH2, with 250MS/s real-time sampling rate. Time base ranges from 10ns to 20s, with ยฑ400V maximum input voltage and built-in protection. Advanced features include FFT analysis, XY mode, and mathematical functions. Three trigger modes (Auto, Normal, Single) provide flexible signal capture for debugging and analysis.
Multimeter Capabilities
The integrated True RMS multimeter delivers 0.5% accuracy across multiple measurement types. DC voltage ranges from 1.9999V to 1000V, while AC voltage measures up to 750V. Current measurement spans 19.999mA to 9.999A for both DC and AC. Resistance testing covers 199.99ฮฉ to 19.999Mฮฉ, capacitance from 9.999nF to 99.99mF, and temperature from -55ยฐC to 1300ยฐC with K-type probe.
Function Generator Output
Generate 13 different waveforms including sine, square, triangle, and sawtooth patterns. Frequency adjusts in 1Hz steps from 1Hz to 50kHz, with output amplitude variable from 0.1V to 3V peak-to-peak. Duty cycle adjustment from 0-100% and ~50ฮฉ output impedance make this suitable for circuit testing and component characterization.
Upgrades from Previous 2C23T Model
The 2C53T delivers significant improvements over the 2C23T: 5ร faster oscilloscope bandwidth (50MHz vs 10MHz), 5ร higher sampling rate (250MS/s vs 50MS/s), and 2ร multimeter precision (19,999 vs 10,000 counts). Additional upgrades include an extra oscilloscope probe, FFT/XY/Math functions, and premium carrying case.
