Oscilloscopes & Bench Test Equipment

Matching Analogue Bandwidth and Sampling Rate

Evaluating an industrial digital oscilloscope begins with bandwidth and real-time sampling rate. Capturing high-speed transitions without distortion requires adequate frequency headroom across all active channels. Our benchtop instruments provide bandwidth ratings such as 70MHz in the 6074BE series up to 250MHz in model 6254BE, while model 1014D delivers 100MHz analogue bandwidth per channel. When testing multi-channel systems, check whether bandwidth divides across inputs. For instance, DSO3D12 maintains 120MHz with CH1 only, dropping to 60MHz with CH1 and CH2 active.

Real-time sample rate directly dictates transient capture accuracy. Bench units achieve up to 1GSa/s real-time capture, while portable platforms deliver rates ranging from 2.5MS/s in DSO152 up to 250MS/s in 2C53T. Fast edge evaluation also demands low rise time, such as under 3ns found on DSO3D12.

• Bandwidth coverage across models: 200kHz, 1MHz, 10MHz, 20MHz, 24MHz, 50MHz, 70MHz, 100MHz, 120MHz, 150MHz, and 250MHz
• Sampling capacity: Real-time acquisition from 2.4MSa/s up to 1GSa/s
• Input impedance ratings: Standard 1MΩ, 25pF or 250kΩ / 15pF configurations

Selecting Benchtop Hardware versus a Handheld Oscilloscope

Field maintenance requires different equipment profiles than fixed electronics production benches. A dedicated benchtop digital oscilloscope offers large front-panel controls, mains power and deep waveform memory. For field service and control panel troubleshooting, a handheld oscilloscope or an integrated oscilloscope multimeter combines multiple service tools into one portable housing.

Compact hybrid tools minimize carry weight while maintaining diagnostic scope. The dual-channel 2C53T combines an oscilloscope, multimeter, and signal generator into one chassis with 250MS/s sampling. Field units like DST-210 deliver 19999 Counts TRMS metering alongside scope functions, with scope inputs up to 800Vpp on a 10:1 probe.

• Bench signal generators: AC 100-240V powered units such as the 24MHz dual-channel generator, measuring 280 x 220 x 85 mm and weighing 2.1 kg
• Field portability: Handheld units featuring 2.8in screens and battery power
• Hybrid test capacity: handheld oscilloscope multimeters with 19999-count True RMS metering

Integrating a Signal Generator, Logic Analyser, or Spectrum Analyser

Modern troubleshooting frequently requires stimulus-response testing where generating known reference signals is mandatory. Pairing oscilloscopes with an arbitrary waveform generator or dedicated function generator allows technicians to inject clean sine, square, triangle, or pulse waves into circuits under test. The UTG932E supplies frequency generation up to 30MHz, while the UTG962E reaches 60MHz with 14-bit vertical resolution and 200MSa/s sampling.

For mixed-signal firmware debugging and bus verification, logic analyser hardware captures high-density digital communication lines simultaneously. Units such as DLA-16 Plus or DLA-32 Plus trace multi-channel digital logic states across complex microcontrollers. When assessing RF signal distribution or harmonic distortion, a spectrum analyser or vector network analyser such as LiteVNA 64 or NanoVNA-H4 validates high-frequency impedance matching across transmission lines.

• Signal generation: Arbitrary waveform outputs covering 24MHz, 30MHz, 60MHz, and up to 100MHz
• Digital bus decoding: High-density logic analyser configurations including DLA-16 Plus and DLA-32 Plus
• RF characterization: High-frequency analysers including LiteVNA 64, NanoVNA-H4, and DeepVNA 101
