1700．FEATURES :

PC Microcomputer  Based

Curves displayed in various colors. Serial & Parallel  port is provided. Printer can be connected with 1700,  to print out all the charts &  records displayed on the screen.

Professional Software . Truly comply with Every National Standards

As the standard of each nation differs from one to another, thus, if  an  universal applicable software was made, to let the user modify

  by  himself  the test conditions & upper/lower limits as per required  by  each nation's  standard, it is not only  quite troublesome to the

  user, also,  user can make mistakes quite easily.

  Thus,Sunlight provides one corresponding software for each  specific National Standard.When operate, the software can

   automatically set the test conditions： Feeding Bridge Voltage, Serial Resistance, Current, Coupling  Capacitor, Terminal  Impedance,

   Mouth Sound  level and ACV of  Receiving  and Return Loss test are all automatically set by software, to avoid any mistakes made by

   manual setting. When another software was  used, all test conditions were automatically changed to the corresponding  specific

   National  Standard.Quite convenience to  use, especially  when frequent changing of different National Standards is required.

Ex. 1：British BS6317 requires： STMR shall be ≧ ( SLR + 1.5 ) dB or ≧ 7dB ,thus, the correct test mode is  to test first the SLR, then

   add  1.5dB , before it can  be compared with the tested  STMR. If only  STMR was tested,then correct judgement on PASS / FAIL

   could not be obtained.Thus, Sunlight's software for BS6317 can automatically  test first the SLR before testing  STMR, then, it will

   automatically check whether  if  STMR ≧ ( SLR + 1.5 ) or ≧ 7dB ,as long  as one condition was present, PASS judgement would

   occur.

Ex. 2：Taiwan standard requires：To test R distortion, it can  be tested only  when  100dB SPL were produced by the Receiver.Thus,

   to test RLR,1700's software will automatically set ACV = 251 mv ,but while testing R distortion,it will automatically loosen ACV up to

   100dB, so that its distortion can then be tested automatically.

Ex. 3：To test the LR or RE of the telephone based on either British BS6317 or China Standard,The software will automatically  set the

   Terminal Impedance at 600Ω , but while testing the Return Loss, it will automatically switch to two different built-in complex

  Impedances, &  no longer  using the 600Ω ,so as to comply with the standard of the two countries.

The above 3 examples have proven that 1700 can truly &  fully comply with every National Standards, user don't have to undergo further study on every National  Standards, in order  to set the test conditions & limits by himself, thus, any mistakes made by user's setting can be avoided.

Test Conditions and Upper/Lower limits can be set and be modified by user

The software of 1700  has a "Setting" function,which allows the user to modify the test  conditions or Upper / Lower limits : the

  Voltage, Current, Serial Resistance, Coupling Capacitance, Terminal Impedance,Mouth  Sound  Level  and  ACV  etc.  can  all  be  set

   by  the user,  user can even use the Zext Terminals,  to make unlimited  expansion on  the Terminal  Impedances.

The only  exemption : As  the  German standard is quite complicated, if  let the user set the test conditions by himself, user    might

  make  mistakes  quite easily, thus,  software for German  standard "can't  make self-setting〞.In fact,user don't  need  to  make

  self-setting  on  the test conditions & limits, since all the test conditions & limits  are preset  in the software already,thus, User can

  use it  directly  without prior setting.

1700 High flexibility、Powerful Functions

Can test practically almost all the National Standards around the world. Besides,can test so many items , ( Ex.:  Software  for German standard can perform  as many test items as B & K  6711 does ).1700 have the unbeatable 〝(performance ＋ quality) / price〞in ratio.

"Prompt" messages always on the screen  •  Mistakes can be avoided

Sunlight have undergo further study on various National Standards , and have the specific National  Standard  loaded  individually in

   a  3.5〞software disk, user  don't need to make any  prior modification or setting, and can use the software disk directly ：Just insert

   the disk into  1700's FDD,  the telephone's testing  can  then be performed.When using, the screen will display  first the 「Prompt」

   message ,to remind  the user on  what particular Artificial Line,Artificial Ear  shall  be used for specific National Std. and what is the

   correct position of  Artificial Mouth...., to avoid  making any mistakes.

During the test, 「Prompt」messages also appeared on the screen, to ensure correct using, please refer to the colorful  figure on  page

   13 . 「Prompt」messages are automatically displayed on the screen, each  National  Standard displayed different 「Prompt」message,

   so as to comply with different Countries Standards.Beginner can operate 1700 very well even without studying the operation manual.

High Resolution•High Test Speed•The world No.1 Test Speed

  High Resolution : Has Two test speeds, fast & slow can be selected. The freq. interval for slow mode is 1/48 oct., practically near the

   continuous sweeping. While fast mode is 1/12 oct. ,very fast test speed. (1/12 or 1/48 oct. means  1700 when  testing the freq.

   response, the tested  sweep freq. points density in  every double  frequency interval,  to test 12 points  is known  as 1/12 oct.

    sampling points .But 1700 , when  used for calculation of  LR, it will automatically get 1/3 oct. points  from the 1/12 oct. sampling 

   points, to calculate the LR, this is in accordance  to ITU-T (former CCITT) recommendations which required  that only  1/3 Oct. points

   must be  used for calculation of  LR.  But for  freq. response test , 1/3 oct.freq. interval can't be used, since too few freq.points will

   cause the missing of the "Dip" existed in the curve, without the "Dip", wrong  judgement on  freq. response limit  will occured ).

    ( See Note 1  ).

  High Test Speed•The  world  No.1 Test Speed：Ex.,Only 8 seconds are required if Sending, Receiving, Sidetone Loudness Ratings ,

    Frequency Responses and DC-IV characteristics (totally 13 parameters and curves)  of a telephone set are measured under   0Kft  &

    15Kft  line con-ditions, using EIA standard .

Note : the Frequency Response measurement is done in 1/12 oct. high resolution, & not the 1/3 oct. low resolution.With such  a  fast

          speed, we can say that  1700 has the fastest test speed around the world .

  The faster the test speed, the lesser the number of instrument is needed, thus, 1700 have the "unbeatable (performance ＋ quality)

  Price" in ratio, since one of  the  reasons is that 1700 has the world No.1 test speed.

To evaluate the test speed of  an  instrument , it is not enough to consider only on 〝How fast to sweep a curve？〞, But also on：(a)

   Resolution on frequency points (see Note 1). (b) Degree of automation on performing  the sequential  test on various items

   (see Note 2)

Suitable for using in R & D、QA、QC、and production line

Has the built-in automatic Tracking Filter, can reduce the  effect of  environmental  noise. When used in a noisy production line, don't

  have to worry  that the test results will  be affected by the  environmental noise.

The dB values of a  curve, or dB difference between the new curve and the freezed  curve, can be read directly with the help of the

   cursor, no need  of manual calculation.Suitable for  R&D  use, to make comparison and analysis before and after the Telephone have

   been modified.

1KHz ( 0Km ) electrical and sound signals are provided for the adjustment of Receiving Sensitivity and  Sending FM deviation of the

  cordless  phone  , after adjustment,the instrument  will  turn to sequential test automatically.

Type 1700 Class H  is provided  with one free calibrator CTR－7 (1700 Class L not provided ).As 1700 is quite stable, thus, calibration

   once a year is enough. CTR－7 can be used for calibrating all classes of  1700.

All Softwares for Type  1700  H & L have the statistical function.Automatically make statistical analysis on the tested telephones daily

  done in the production  line , 6 pages of statistic report can be stored permanently in the disk (One statistic report per day, each disk

  can be used in  one  week),statistic report can  be recalled anytime for  viewing  or printing-out.  

Note 1: (a) Resolution on Frequency points：

Some brand of  Telephone  Analyzer  uses 1/3  oct. sweep frequency density for freq.  response  measure-ment, regardless how fast the test speed is,it will not be accepted  by "Almost all the   National  Stds.". Since its resolution is too low, "Dip"  existed in the curve could be missed, bad quality  phone will be judged as pass one (see right Fig.):  0 & 4 appeared as a straight line, while 1-2-3 points have no "Dip" existed in the curve,  but when 1/12 oct. is used, 0-1-2-3-4 completed curve can   be  displayed, misjudgement can be avoi-ded, Thus, 1700  never use 1/3 oct. for freq. response measurement.

Note 2: (b) Degree of automation on performing  the sequential  test on various items

As Ex. 1 of  page 1 stated： If one instrument can't  perform  as  fully automatic testing as example  1  stated, then, user have to test first the SLR, record down the  SLR value manually, add 1.5 to SLR, then  STMR can be tested, and then, determine manually  whether  if STMR  was ≧ ( SLR + 1.5 ) or ≧ 7dB.In  this case, eventhough  the test speed of SLR、STMR are fast, but the overall test speed (addition of  manual  test time  ,＋1.5, &  judgement time) will still be very  slow
