In the Memory Scan mode, the receiver settings can be programmed for the monitoring of up to 10000
channels. These channels can be scanned with the "Memory Scan" command. A single channel can be
called with the "Recall" command.
The squelch level serves as a criterion for dwelling at the same frequency or switching to the next
channel. lf the level criterion is met, the receiver allows for the selectable dwell time to elapse and then
switches to the next channel.
Parameters selectable for each channel:
 Memory location status
 Frequency
 Demodulation mode
 Bandwidth
 Attenuator
 AFC settings
 Squelch parameters
 Antenna number
The "Continue" command can be used to switch to the next channel before the dwell time has elapsed.
In the Frequency Scan mode "Start Frequency", "Stop Frequency", and "Frequency Step" are defined
for monitoring a specific frequency range. This frequency range can be scanned with the "Frequency
Scan" command.
The squelch level serves as a criterion for dwelling at the same frequency or switching to the next
frequency. lf the level criterion is met, the EM510 allows for the selectable dwell time to elapse and then
switches to the next frequency. The demodulator settings are fixed for the defined search range. The
"Continue" command can be used in this case to switch to the next frequency before the dwell time has
elapsed.
In Memory Scan or Frequency Scan mode a selectable number of different measurements (e.g. level
offset, AM modulation index, FM deviation, bandwidth) are performed in parallel.
In the Panorama Scan mode the receiver is tuned from start to stop frequency in nearly 10 MHz steps,
performing a high resolution FFT at each step. The resolution bandwidth covers a range from 125 Hz
up to 100 kHz, resulting in an outstanding scan speed of up to 600000 Ch/s or 16 GHz/s.
In the "Fixed Frequency Mode" a comprehensive selftest of the receiver can be performed. The test
can be carried out in full or in a shorter version with only "GO" or "NOGO" being issued.
