Sondy prądowe Tekbox TBCP1 25 mm

Product overview

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

TBCP2-250 is an RF probe for current monitoring. The probe has a very flat characteristic with a 3dB frequency response of 250 MHz and is characterized over a frequency range of 30 kHz to 300 MHz. On request, it can also be supplied with a test protocol covering the frequency range from 1 kHz to 350 MHz. The aperture of the RF probe for current monitoring is 32 mm. Its frequency response impedance is > 12 dB Ohm from 700 kHz to 300 MHz.

TBCP2-500 is an RF probe for current monitoring. The probe has a flat characteristic with a 3dB frequency response of 500 MHz and is characterized in the frequency range from 30 kHz to 600 MHz. On request, the test protocol can be extended to frequencies up to 1 kHz. The aperture of the RF probe for current monitoring is 32 mm. Its transmission impedance is > 15 dB Ohm in the range from 1 MHz to 500 MHz.

TBCP2-750 is an RF probe for current monitoring. The probe has a very flat characteristic with a 3dB bandwidth of 750 MHz and is characterized in the frequency range from 30 kHz to 800 MHz. On request, the test protocol can be extended to frequencies up to 1 kHz. The aperture of the RF probe for current monitoring is 32 mm. Its transfer impedance is > 15 dB Ohm in the range from 1 MHz to 750 MHz.

TBCP2-30K400 is an RF probe for current monitoring. The probe has a very flat characteristic in the range from 30 kHz to 500 MHz and is characterized in the frequency range from 10 Hz to 500 MHz. The TBCP5-30K400 is designed for RF current monitoring applications where higher sensitivity at low frequencies is required compared to other series of current monitoring probes. The higher sensitivity at low frequencies comes at the cost of a slightly reduced overall transimpedance.

Tekbox also provides calibration instrumentation corresponding to the TBCP2 current probe series.

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.
