Ciprian Alexandrescu Posted November 9, 2009 Author Share Posted November 9, 2009 Acestea nu sunt izolate galvanic ..unele le stiam si eu..oricum multumesc pentru raspuns. Link to comment
Ciprian Alexandrescu Posted November 9, 2009 Author Share Posted November 9, 2009 De asa ceva am nevoie dar la un pret romanesc. http://www.cheele.cn/data/skins/chinese024/eng_01.htm Link to comment
lorik199 Posted December 4, 2009 Share Posted December 4, 2009 nu mi se pare un pret exorbitant acelaniste sonde normale costa 150 leiacelea ca sunt 130 $ (~400lei) nu mi se pare un pret enorm.... Link to comment

walyd Posted December 8, 2009 Share Posted December 8, 2009 am gasit o descriere a lor sunt copie fidela a celor philips de la osciloscopul PM9352 am sa incerc sa-ti pun descrierea aiciProbesTastköpfePhilipsPM9352Der aktive Miniatur-Tastkopf PM 9352 ist sehr klein und leicht.Er benötigt zur Stromversorgung entweder das Netzteil PM 9346 (nicht im Lieferumfang enthalten) oder man betreibt ihn mit einem Philips-Oszilloskop mit entsprechendem Stromversorgungsausgang wie z.B. PM 3250/51/52/53 bzw. PM3370 / PM3372 / PM3332 / PM3334.Bandbreite: DC bis 230 MHzAbschwächung: 1 : 10Eingangswiderstand: DC = 110 kOhm - AC = 100 kOhmStromversorgung: +24 V/ -24 VEin Datenblatt zu diesem Artikel finden Sie hier.The Micro-Miniature Probe Philips PM 9352 is very small and lightweight.It only works together with a suitable power supply such as PM 9346 (not included) or can be used together with a Philips oscilloscope with a matching voltage output such as PM 3250/51/52/53 or PM3370 / PM3372 / PM3332 / PM3334.Bandwidth: DC to 230 MHzAttenuation: 10 : 1Input impedance: DC = 110 kOhm - AC = 100 kOhmProbe power requirements: +24 V/ -24 VPlease find a corresponding data sheet here.

Ciprian Alexandrescu Posted December 9, 2009 Author Share Posted December 9, 2009 Ok..multumesc walyd ..din pacate eu am nevoie de ceva care sa suporte cel putin 1kv si sa fie cu intrari diferentiale..nu-mi dau seama exact dar cred ca sonda ta este o sonda standard activa.Pt.lorik199 ..pretul este ~380$(sus este pentru amplificatorul diferential cu izolare) iar aici la mine cu tot cu transport ar ajunge pe la 500:cry: Link to comment
