|---|---|---|---|---|---|---|
| 369876 | Recalling the SFP configuration in an error state does not update the values in the display area. If you save an NI-RFSA SFP configuration while the NI-RFSA SFP is in an error state, when you recall the configuration, the NI-RFSA SFP does not update the display area with the values from the file. Workaround: Change the value causing the error after you recall the configuration.
| |||||
| 379030 | The offset value displayed by the Select Offset button is incorrect in certain cases. For adjacent channel power measurements and spectral emission mask measurements, if you specify an offset value between 13 and 15 using the Select Offset button, the button displays an offset value that is incremented by one. The NI-RFSA SFP uses the offset value that you specify in the Select Offset button to configure the offset, but displays an incorrect value. For example, if you specify 13, the Select Offset button displays a value of 14, but the Soft Front Panel displays the configuration for the offset of 13. Workaround: Use the value that you specify in the Select Offset button for editing and viewing the configurations. Ignore the value displayed in the Select Offset button.

| 379671 | The External Digital trigger behaves incorrectly, and cannot be disabled after switching measurements. Triggering does not work correctly when you switch from spectrum measurements (all measurements off, channel power, occupied bandwidth, adjacent channel power, TOI, or spectral emission mask) to zero span, transmit power, or CCDF measurements, while the External Digital trigger is enabled. Also, you cannot disable the External Digital trigger using the Free Run button if you enable the External Digital trigger while specifying a spectrum measurement, and then switch to zero span, transmit power, or CCDF measurements. Workaround: Disable the External Digital trigger in spectrum measurements before switching to zero span, transmit power, or CCDF measurements. If you specify zero span, transmit power, or CCDF measurements after you have enabled the External Digital trigger, switch back to any spectrum measurement or click the All Meas Off button. Disable the External Digital trigger, switch back to zero span, transmit power, or CCDF again, and reconfigure the External Digital trigger.

| 346518 | A delay occurs if you use the mouse to move a marker when there are many points on the graph. In Spectrum mode, with a large span to RBW ratio or in Zero Span mode with a large RBW or acquisition time, when you enable a marker and move it using the mouse, events queue up and there is a delay until all the events are processed. You may also experience a delay when clicking the arrow keys. Workaround: Change the marker position by entering a new marker value using the keypad instead of the mouse or arrow keys.

| 387636 | Reference level cannot be set below 0 dBm when the IQ Power Edge Trigger is enabled. When enabling the IQ Power Edge Trigger, or enabling transmit power measurements (which turns on the IQ Power Edge Trigger by default), the reference level cannot be set below 0 dBm. If a value less than 0 dBm is specified, an error will be returned that the configured trigger level value is too high even though the trigger level value is less than the configured reference level. Workaround: Disable the IQ Power Edge Trigger or increase the reference level.
| |||||
| 368610 | Warning continues to display after you decrease the power level at the input. When the reference level of the NI-RFSA SFP is set below the power level of the signal being generated, a warning displays. If you decrease the power level at the input, the warning continues to display until you change the reference level. Workaround: Click the Clear button.

| 375392 | The NI-RFSA SFP acquisition waits on the trigger even after the IF Filter is coerced to free run. When performing an I/Q triggered acquisition, if you change the IF Filter from Automatic or Through to one of the manually set bandwidths, the trigger value is coerced to Free Run. The device continues to wait until the I/Q power edge trigger is received. Workaround: After changing the IF Filter, manually set the trigger value to Free Run or change any other parameter, such as frequency or reference level.
| |||||
| 339218 | Acquisition does not begin immediately after you clear a PLL lock error. When the NI-RFSA SFP is set to use an external Reference clock which is not connected, a PLL lock error occurs. After you connect the clock and the device locks to the clock, the error clears, but no data displays until you change a setting in the soft front panel. Workaround: Change a setting in the soft front panel or click the Restart button, after the PLL lock error clears.
