JAGUAR incorporates a built-in scanner to produce detailed offset histories for all or selected frequencies. This scanner can be used in the LIVESCAN or FILESCAN mode.
While LIVESCAN can analyze the selected frequencies in the LIVE mode as long as the Perseus hardware is connected, FILESCAN can be used for collecting offset history data later from the recordings. Typically, you can do all the scans you need "on-the-fly" using LIVESCAN, but if you didn't have that option available in the LIVE mode, then you still have a chance to generate the spectrum history using FILESCAN.
What comes to performance, LIVESCAN is however superior in speed. Running FILESCANs can take a long time, depending on the amount of files and the number of frequencies to be scanned.
FILESCAN can be started by clicking the SLIDER > SCAN button when you are in the ARCHIVE mode (in the LIVE mode this button triggers the LIVESCAN settings):
You can define the following parameters for FILESCAN:
When the parameters have been set, a FILESCAN run can be started by clicking the RUN button.
FILESCAN uses an external FILESCAN.exe program (included in the JAGUAR full package). JAGUAR will show the progress of the scan on the STATUSBAR.
FILESCAN can take a long time before finished. You can increase the speed allowing some potential spurious carriers mixed in the results, but having still generally good results. SPECTOR can be used to spot those spurious signals: missing peak in SPECTOR at the position of the spectrum track reveals a spurious carrier. If you want to utilize this improved speed, please define SETTINGS > KIT > OPTIONAL > HI_QUALITY > NO before you start the FILESCAN run.
Just as with LIVESCANs, the results of FILESCAN can be zoomed/viewed on the HISTORY spectrum displays. Whenever you run a new FILESCAN, the results will replace the earlier scan data for the target frequency/frequencies.
You can use the keyboard key "E" to toggle the current HISTORY screen and the HOME screen.
