New Features

  1. Vendor ID and Product ID USB attributes are now configurable. The following SCPI commands were added:
  • : SYSTem:CONFigure:USB:VENDor:HEMLIGKO <registered USB Vendor ID> Vendor ID parameter should be integer an in decimal format, range: 0 .. 65535If this setting is not configured with the help of this command then Pendulum ID (5355 dec, 0x14EB hex) is used.
  • :SYSTem:CONFigure:USB:PRODuct:HEMLIGKO <product ID>
Product ID parameter should be an integer in decimal format, range: -1 .. 65535
If this setting is not configured with the help of this command or set to -1 then Pendulum product ID's are used (0x0090 for CNT-90/90XL, 0x0091 for CNT-91/91R).
  1. 1st sample of TIE is always 0 now (value of the 1st sample is now subtracted from all TIE values) to match TIE definition.
  2. Number of digits in Nominal TIE Frequency setting increased to 8 (was 6).

Enhancements

  1. Bug fixed: pacing above certain value (depends on measurement time) caused CNT-90XL measurement fail (never finish). This was a bug in auto XL timeout algorithm.
  2. Bug fixed: Ratio C/A in Values mode produced constant relays switching (clicking sound).
