Longest scope probe: 7 metres and 1.5GHz bandwidth

Tektronix has taken its TAP1500 1.5GHz active single-ended probe, and stretched its 1.3m cable to seven metres “with no loss in performance”, according to the company.

TAP1500L is the name of the extended version.

“Our customers can’t always have their oscilloscopes close to their device-under-test,” said Tektronix probe manager Andrew Mumford, “and the longer cable benefits customers who use flying probe testers that require long cables for routing through automated positioning systems.”

Rise time is <267ps and input capacitance is ≤1pF input capacitance.

The probe head is designed to reach small components, and its probing accessories are designed to work with surface-mount components down to 0.5mm pitch.

Electronics Weekly has yet to see the L-version data sheet – the shorter non-L version has 1MΩ input resistance, -8V to +8V input dynamic range and -10 to +10Vdc input offset range.

For the probe to work with a scope, the instrument has to have Tektronix’ ‘TekVPI’ interface, which both supplies power to the probe and sets up the scope appropriately.
