Sondy prądowe Tekbox TBCP1 25 mm

Product overview

The Tekbox TBCP-2 probes are a series of four current probes with a fixed aperture of 32 mm. Available models:

TBCP4-250 is a fixed aperture RF current probe. It features very flat characteristics with a 3dB frequency response of 250 MHz, and can be used in the frequency range from 10 kHz to 250 MHz. The aperture of the RF probe for current measurement is 32 mm. Its frequency response impedance is close to 14 dB Ohm in the range from 400 kHz to 250 MHz.

The TBCP4-500 is an RF current measurement probe with a fixed aperture. It has very flat characteristics with a 3dB frequency response of 500 MHz and can be used in the frequency range from 10 kHz to 500 MHz. The aperture of the RF current probe is 32 mm. Its frequency response impedance is close to 16 dB Ohm in the range from 400 kHz to 500 MHz.

The TBCP4-750 is an RF current measurement probe with a fixed aperture. It has very flat characteristics with a 3dB frequency response of 750 MHz and can be used in the frequency range from 10 kHz to 800 MHz. The aperture of the RF current probe is 32 mm. Its frequency response impedance is close to 20 dB Ohm over the range from 400 kHz to 750 MHz.

Tekbox also offers a calibration mount corresponding to the TBCP4 series of fixed-aperture current probes.

Calibration handles

TBCP1_CAL, TBCP2_CAL, TBCP3_CAL and TBCP4_CAL are calibration holders corresponding to the TBCP1, TBCP2, TBCP3 and TBCP4 series of RF current probes. - See the "Models to choose from" list.

The RF current probe calibration fixture is used in conjunction with a vector network analyzer
or a spectrum analyzer equipped with a tracking generator to measure the transfer impedance of RF current probes.
Each Tekbox RF probe is supplied with a corresponding calibration sheet containing frequency-dependent transfer impedance values. Therefore, there is no need to purchase calibration instrumentation along with the probe. The calibration fixture can be used for periodic inspection of the probes or to check the condition in case the probe has fallen and there is a suspicion that its ferrite core may have been damaged.
