High-voltage differential probe for oscilloscopes

The Pintech N1140Apro is a 50 MHz bandwidth differential probe rated for 14 kV peak-to-peak measurement. It converts floating two-point signals to ground-referenced outputs for oscilloscopes and data acquisition systems. Selectable 100X and 1000X attenuation ratios suit motor-drive and power-electronics testing.

Sustained-load behaviour and accuracy

Accuracy is specified at ±0.5 % from DC through 50 Hz to 1 kHz after a one-to-two-minute warm-up. The 7 ns rise time and 36 MΩ // 1 pF differential input impedance maintain signal fidelity during extended captures. Common-mode rejection exceeds 80 dB at 60 Hz and 50 dB at 100 kHz, limiting error from ground offsets during long sessions.

BNC interface and power constraints

The probe terminates in a BNC connector on a 90 cm cable for direct connection to a 1 MΩ oscilloscope input. A 6 V DC 300 mA mains adaptor powers the active circuitry, so a suitable outlet is required. Input leads are 30 cm long, and the unit weighs 425 g in a 187 × 83 × 41 mm housing.

Questions about this item

How much power does the N1140Apro draw from its 6V DC mains adaptor during all-day use?

The probe is supplied with a 6V DC, 300mA mains adaptor, so continuous operation draws a modest 1.8W from the wall outlet.

Which oscilloscope input impedance must the buyer already have for the probe to meet its ±0.5% accuracy spec?

The probe is calibrated for a 1M oscilloscope input; using a 50 ohm input would alter the attenuation ratio and degrade the stated accuracy.

Can the 90cm BNC cable reach the front panel of a typical bench oscilloscope without an extension?

At 90cm the cable reaches most bench scopes directly; if the instrument sits further back, a standard BNC extension can be added without affecting the 50MHz bandwidth.
