7 The Virtual Device... Smetimes, when cnstructing a system r subsystem, yu cannt find a device that prvides quite the functinality that yu require. Assume yu need a large attenuatin range, but a small incremental step size. Typically, ne wuld be frced t use tw physical attenuatrs cnnected in series t achieve this gal. Fr example, let's assume there is a requirement fr an attenuatr with a ttal attenuatin >80 db, with a reslutin f 1dB ver the dc-18 GHz frequency range. One culd cmbine a Mdel 150T /10 db steps) with a Mdel 150T /1 db steps) t meet this gal. Unfrtunately, the prgramming burden has increased dramatically, since yu must nw nt nly write the sftware t cntrl tw separate devices, but als develp an algrithm fr determining the apprpriate settings fr each device. In additin, if yur requirements were t change perhaps t a larger attenuatin range, r a different step size, these algrithms wuld have t change accrdingly. The 8210A prvides a slutin t this dilemma with the ability t create and define a virtual device. A virtual device allws the user t cnstruct a device by cmbining the attributes f several physical devices, and be able t prgram this cmbinatin as if it were ne physical device! Revisiting ur example abve, we can create a virtual attenuatr with an attenuatin range f 81/1 db steps, effectively creating a 150T-81. Cntrlling this new device requires n mre prgramming than cntrlling a single attenuatr. The 8210A supprts up t 32 virtual attenuatr devices, each f which allw up t fur physical attenuatrs t be cmbined int a single device. The virtual attenuatr uses the Attn Prtcl cmmand set, prviding the same prgramming interface as ther attenuatr devices. During the setup prcess, the user assigns a name t the virtual attenuatr, which may be stred in the 8210A's nnvlatile EEPROM memry fr future use. During the pwer-up cnfiguratin prcess, the 8210 will autmatically recall and assign these virtual devices. The SmartStep Apprach... Using Weinschel s Smartstep apprach a custmer can easily design and layut subsystems in minutes that includes a wide range f Plug & G prgrammable attenuatrs and ther standard micrwave and RF cmpnents which can be cntrlled ver varius standard cmmunicatins interfaces.

10 Lw Intermdulatin Subsystems & Signal Cnditining Netwrks... Sme custm subsystem designs warrant the use f Lw Intermdulatin passive cmpnents such as prgrammable attenuatrs, terminatins, fixed attenuatrs, cuplers, cables, cnnectrs and switches. Weinschel is a leading manufacturer f the first three items. The fllwing paragraphs briefly describe the imprtance f lw intermdulatin and sme design features and cmparative test data fr the same. Prgrammable Attenuatrs Histrically the mst demanding specificatins fr prgrammable cmpnents and subsystems have been lw insertin lss and SWR, cmbined with a reasnable life expectancy f several millin switching cycles. This was usually adequate fr RF instruments like spectrum analyzers and signal generatrs, where the attenuatr bandwidth rather than the switching speed was f prime cncern. T achieve wide bandwidths, the prgrammable attenuatrs were mstly f electrmechanical design and the linearity f these passive cmpnents was nly taken fr granted. Intermdulatin distrtin discussins and prblems were usually limited t cmpnents such as amplifiers, mixers and filters. In recent years, hwever, wireless cmmunicatin systems emplying cmplex digital mdulatin schemes, increased channel capacity, high transmit pwer and extremely lw receiver sensitivity have put int questin the linearity f passive cmpnents. Even very lw level multi-tne intermdulatin prducts generated by attenuatrs can seriusly degrade the efficiency f a system/instrument if these prducts fall within the user passband. Fr tw clsely spaced tnes at frequencies f1 and f2, the third rder IM prducts at 2f1 - f2 and 2f2 - f1, are the mst harmful distrtin prducts. They are harmful because they are clse t f1 and f2 and virtually impssible t filter ut. In tday's base statins the multi-carrier pwer amplifier (MCPA) is replacing banks f single-channel amplifiers and their crrespnding pwer cmbining netwrk. MCPAs have the capability f carrying a number f mdulatin schemes simultaneusly and can als emply schemes such as dynamic channel allcatin (DCA) t use the allcated frequency spectrum mre efficiently. The in-band intermdulatin distrtin (IMD) perfrmance f these amplifiers is extremely critical and needs t be measured using lw distrtin prgrammable multi-tne generatrs with superir IMD perfrmance. Thrugh IM3 (dbm) IM3 Perfrmance f Electrmechanical & Slid State Prgrammable Attenuatrs Passive IM3 Measurement Weinschel Series 4206, 4216, 3200 & 150 Lw Carrier Frequency: MHz High Carrier Frequency: MHz IM3 Frequency: MHz PIN switched series FET switched series TO5 rela y switched series Edge-line reed switched 150 series Input Pwer, P in (dbm) each tne Electrmechanical prgrammable attenuatrs bviusly prvide a far superir IMD perfrmance than their crrespnding slid state cunterparts emplying semicnductr switching elements. Hwever, their slw switch speed, in the rder f milli-secnds, and shrt switch life in the rder f 5-10 millin cycles make them unattractive in sme applicatins like cell phne testing and ther ATE systems. Slid State prgrammable attenuatrs d vercme these tw prblems and are, therefre, included here fr IMD perfrmance cmparisn. The gal is t prvide sme gd basic IMD test data fr a variety f cmmercial prgrammable attenuatrs and permit the end user t select the mst apprpriate type fr his system applicatin. Fixed Attenuatrs & Terminatins These seemingly linear cmpnents generate lw levels f IMD which must be cnsidered, especially when incident pwer levels are high. Sme f Weinschel custm subsystem designs include lw IM versins f medium and high pwer fixed attenuatrs and terminatins. These cmpnents are supplied with specified 3rd rder thrugh and reflected intermdulatin levels (IM3) measured with a passive IM analyzer. Typically, the IM3 levels fr these cmpnents are -110 dbc. Standard Mdels with this LIM (lw IM) ptin are mdels 33, 24, 49, 53, 57, 58 and the crrespnding terminatins, ranging in incident pwer ratings f 25 t 500 Watts. Features f these cmpnents include specifically designed cnnectrs and carefully prcessed and trimmed thin film resistrs fr lw IM perfrmance. Cuplers, Cables, Switches, Cnnectrs, etc. Althugh Weinschel des nt manufacture these cmpnents we wrk very clsely with ur suppliers, prviding them pertinent design input t achieve the lwest pssible IMD perfrmance n such prducts. 170 web: sales@weinschel.cm

18 MODEL 8312 SmartStep TM High Pwer Prgrammable Attenuatr IEEE-488 RS232\RS Watt Ht Switching Capability Descriptin MCE/ Weinschel's design apprach uses a highly adaptable platfrm that allws cnfiguratin f the step attenuatr t the custmers requirements. When the cntrller requests a new attenuatin level the input switch terminates the input signal int a 50 Ohm lad. (See Figure 1) This input switch is ht switchable at 100 Watts f input pwer. This will remve the high pwer signal frm the main signal path. With n signal cnnected t the attenuatr path the cntrller then cmmands the series f relays t cnfigure the attenuatr fr the requested attenuatin value. Then the input switch re-cnnects the input signal t the attenuatr path. The system can be perated with either a remte cntrller (IEEE-488 r RS-232) r thrugh frnt panel cntrl.
