Generator de semnal PCGU1000 Velleman

Recommended Posts

Am achizitionat de pe ebay un generator de semnal PCGU1000 fabricat de Velleman de la un neamt. Mi-a spus ca a desfacut pachetul doar sa-l incerce, iar la intrebarea mea daca functioneaza corect, mi-a raspuns ca da.

Am primit pachetul, am bagat in priza alimentatorul(tensiune verificata de 9,8V), am alimentat generatorul si am avut prima surpriza: led-ul de ON/READY nu s-a aprins.

Am conectat generatorul la PC printr-un cablu USB, moment in care a fost detectat de claculator. Am instalat programul PcLab2000SE_v4_05, precum si driverele pentru WIN7. Am pornit programul, dar mi-a aparut urmatorul mesaj:

"No function generator response. Please make sure that the USB cable is conected. If conected: Disconnect and reconnect the USB cable.

Program will be closed." 

Cand verific PCGU1000 Properties/General, apare urmatorul mesaj:

"Windows cannot verify the digital signature for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.(code 52)".

Nu functioneaza generatorul sau sunt eu prea fraier si nu stiu sa-l instalez(program+drivere)? E foarte posibil sa fie a doua varianta, caz in care va rog sa-mi dati ceva idei... Asta inainte de a-l lua pe neamt la bumbaceala   :whistling:

Multumesc anticipat!

buna seara 

A trecut ceva timp de cand a-ti postat si poate a-ti rezolvat intre timp

in principiu se intampla de la drivere

si inca ceva , sa aveti instalat inainte net. framework 4.0 , in functie de performantele calculatorului se poate urca mai sus 

Poate ajuta
