This issue may happen for certain combinations of Center Freqency, Span, Resolution Bandwidth, Video
Bandwidth and Sweeptime and is now fixed.
3. (V4.61) FSQ-K70: Modulation Accuracy – FSK DEV ERROR Peak evaluation does not ignore the
sign of the current value.
As a result negative values are not correctly taken into account.
Improvements with Service Pack 2
Service Pack 2 corrects the following issues. Service Pack 2 includes Service Pack 1.
1. (V4.31) Marker Function Reference Fixed can not be switched off.
It is not possible to switch off the marker function REFERENCE FIXED after follwing order of key
strokes:
- MARKER – REFERENCE FIXED (activates Reference Fixed)
- MKR FCTN – NOISE MEAS (activates Noise Marker)
- MKR FCTN – NOISE MEAS (de activates Noise Marker)
2. (V4.61) The Option Key (de)activation state change is lost after reboot.
Once installed, it is possible to enable/disable an option key in dialog SETUP – GENERAL SETUP -
OPTIONS. A reboot is required for a few options. The message box "The system must be rebooted to effect
the changes. Reboot now?" will be indicated in that case. With versions 4.61/4.61 SP1 the state change will
get lost after reboot.
Improvements with Service Pack 3
Service Pack 3 corrects the following issues. All previous service packs are included.
1. (V4.61 SP2) A measurement in frequency domain does not reach the end of sweep for certain
instrument settings:
- Filter Type FFT
- large Number of Sweep Points (e.g. 30001)
- small Bandwidth (e.g. 100 Hz)
- large Span (above 3 GHz)
2. (V4.61 SP2) Reduced execution speed for Center Frequency/Span changes if a lot of transducer
set files exist on the instruments harddisk,
3. (V4.61 SP2) B10: A GPIB address change for the external signal generator is ignored.
The analyzer application is using the previous address until the external source is switch off
and on again.
4. (V4.61 SP2) FS-K5: An IF Overload condition is indicated after performing the Level & Time Auto
Adjust with certain EDGE signals.
5. (V4.51)
