1 LC Meter S75 and S70 LC meter with S-3 interface S75/S70 LC Meter 0.05 % baic accuracy (S70), 0. % (S75) 5-digit dilay of L, C, and or Tet frequencie to 00 khz (S70) U to 0 meaurement er econd Binning and limit for art orting External caacitor bia u to 40 V S-3 comuter interface GPIB and Part Handler interface (ot.) The S75 and S70 LC Meter meaure aive comonent with a little a 0.05 % error. Thee eay-to-ue intrument are quick to etu, adjut and calibrate. The S75 and S70 are ideal for alication uch a incoming inection, quality control, automated tet and general benchto ue. Front-Panel ilay A 5-digit LE dilay how meaured value, entered arameter, intrument tatu and uer meage. When making meaurement, the major arameter (L, C or ) i hown on the left dilay and the aroriate minor arameter (, or ) i hown on the right dilay. Making Meaurement Meaurement can be erformed at tet frequencie of 00 Hz, 0 Hz, khz, 0 khz and 00 khz (S70 only). A built-in drive voltage can be et to reet value (0., 0.5 and.0 V) or adjuted from 0. to.0 V in 50 mv increment. Meaurement are taken at rate of, 0 or 0 amle er econd. Conecutive reading can be averaged between two and ten time for increaed accuracy. Both erie or arallel equivalent circuit model of a comonent are uorted. Caacitor meaurement ue either the internal.0 VC bia or an external C ource of u to 40 volt. Stanford eearch Sytem hone: (408)

2 S75 and S70 LC Meter Simle to Oerate The ower and flexibility of the S75/70 doe not come at the exene of eae-of-ue. A convenient AUTO meaurement mode automate the election of etu arameter and quickly determine the aroriate device model for whatever comonent i being meaured. U to nine intrument etu can be tored in non-volatile memory for quick recall at a later time. S78 BNC Adater neted) bin have one nominal value and are orted into rogreively larger bin (i.e., ± %, ± %, ±3 %). Sequential bin can have different nominal value, each earated by a ercentage or a nominal value and aymmetrical limit. Binning arameter are alo eaily tored in non-volatile AM for quick etu in roduction environment. Tet Fixture The S75 and S70 have a kelvin fixture which ue two wire to carry the tet current and two indeendent wire to ene the voltage acro the device under tet. Thi revent the voltage dro in the current carrying wire from affecting the voltage meaurement. adial comonent are imly inerted into the tet fixture, one lead in each ide. Axial device require the ue of the axial fixture adater (rovided). Surface-mount device, or comonent with large or unuually haed lead, can be meaured with otional SM Tweezer (S77) or Kelvin Cli (S76). The tweezer and cli attach directly to the LC meter front-anel tet fixture. An otional BNC Fixture Adater (S78) allow you to connect a remote fixture or other equiment through one meter of coaxial cable. Convenient Calibration The S75 and S70 make it imle to comenate for lead imedance and tray fixture and cable caacitance. The null calibration rocedure automatically correct both oen and hort circuit arameter at all frequencie and all range. Binning The S75 and S70 have built-in feature to aid in comonent orting. Thi i eecially ueful for roduction teting, incoming inection, device matching or when you need to tet multile device of imilar value. The meter allow you to ort comonent into a many a ten different bin. The S75 and S70 uort three tye of binning cheme: a/fail, overlaing and equential. Pa/fail ha only two bin; good art and everything ele. Overlaing (or ear Panel S77 Surface Mount Tweezer Two rear-anel inut connection are rovided for an external bia voltage. Voltage a high a 40 VC can be ued. An otional handler interface rovide control line to a comonent handler for orting. A tandard S-3 interface allow comlete control of all intrument function by a remote comuter. A GPIB interface i included with the handler otion.

5 S75 and S70 LC Meter Ideal evice Model All non-ideal aive device (reitor, inductor and caacitor) can be modeled a a real comonent (reitor) either in erie or in arallel with a reactive comonent (caacitor or inductor). The imedance of thee comonent change a a function of frequency. The erie and arallel model are mathematically equivalent and can be tranformed back and forth with the equation hown. The S75 and S70 can witch between either arallel or erie equivalent circuit. Uually one model i a better rereentation of the device under oerating condition. The mot accurate model deend on the device and the oerating frequency. Certain device are teted under condition defined by the manufacturer or indutry tandard. For examle, electrolytic caacitor are often meaured in erie at 0 Hz in the C+ mode, o the ES (equivalent erie reitance) can be meaured. The equivalent erie reitance in caacitor include thing like dielectric abortion in addition to the ohmic loe due to lead. It i often lited on data heet for electrolytic caacitor ued in witching ower ulie. At high frequencie, the ES i the limiting factor in the erformance of the caacitor. The quality factor,, i the ratio of the imaginary imedance to the real imedance. For inductor, a high indicate a more reactively ure comonent. A low indicate a ubtantial erie reitor. varie with frequency. With reitor, often all that i tated i that the reitor ha low inductance. The diiation factor,, i equal to / and i the ratio of the real imedance to the imaginary imedance. A low indicate a nearly ure caacitor. i commonly ued when decribing caacitor of all tye.
