EM510 Characteristics
4065.7763.32-01.00 2.2
2.2 Operating Modes and Control
The Fixed Frequency Mode is the standard mode of the receiver. In this mode a fixed frequency
channel is set at which the signal is received, filtered and demodulated.
The following parameters can be set:
Frequency
Setting range from 9 kHz to 32 MHz in 1 Hz steps
Demodulation mode
The following demodulation modes can be selected:
– FM
– AM
– PULSE (AM PULSE)
– PM
– USB
– LSB
– ISB
– CW
– I/Q
Bandwidth
The IF bandwidths can be selected in 30 steps between 100 Hz and 10 MHz.
Measurement time (automatic or settable between 0.5 ms to 900 s)
Detector modes "continues" or "periodic"
Squelch
The level squelch can be set in 1 dB steps in the range from -30 to +130 dBµV.
AFC (Automatic Frequency Control)
With AFC switched on, the receiver frequency is tuned within the IF bandwidth.
Level detector
For level measurement the detector can be switched to AVG, PEAK, RMS or FAST.
Frequency offset detector
Attenuator
The attenuator operates in manual (0 to 25 dB) or automatic mode.
Gain control (GC)
Automatic (AGC) and manual (MGC) gain control is selectable.
The MGC setting covers the input signal range from -30 to 130 dBµV.
Video Panorama
Spectrum of the demodulated signal with analysis features (squared AM, FM)
IF Panorama (Option)
Independent from IFBW, settable from 10 kHz to 9.6 MHz
ITU Measurement (Option)
AM modulation index (AM+, AM-, AM)
FM deviation (FM+, FM-, FM)
PM deviation (0 to 4π)
Bandwidth (0 to 9.6 MHz)

Characteristics EM510
2.3 4065.7763.32-01.00
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, resultingin 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.

2.3 Design
(see Fig. 2-1: Front View, Fig. 2-2: Rear View and Fig. 2-3: Modules)
The EM510 basically consists of the following modules:
Compact case
AC/DCconverter and power supply
HF receiver module
Fans
The compact case corresponds to the 19” standard and can be fitted into any 19” rack. Two brackets
are provided at the sides for rack mounting.
At the rear on the right the interface and RF connectors are located. Three LEDs located above the
10/100 Base-T Ethernet LAN connector indicate linkstatus and activity. On the left there are the mains
input socket with integral fuse holder and the DC source connector for feeding in the mains and DC
supply voltage. Fuse F3 is for the DC supply voltage. The four feet of the compact case protect the
connectors when the case is set down.
At the front the POWER switch, POWER LED and HEADPHONE socket are located.
The HF receiver module is located in the left-hand part of the chassis. It is arranged in such a way that
the RF connections between the receiver and rear connectors are as short as possible. The interface
connectors aredirectly accessible through an opening in the rear panel. The HF receiver module is
designed as a slide-in module with its own front panel indicators and connectors.
The AC/DC converter and the power supply are located in the right-hand part of the compact case.
The two fans incorporated in the partition panel ensure sufficient cooling of the power supply and the
HF receiver module. There is no temperature-dependent control for adjusting the fan speed.
The fans expel the hot air to the sides. Both side panels are equipped with ventilation slots for drawing
and expelling cooling air. On installing the EM510, sufficient room should be left at the sides of the unit
to ensure an unhindered flow of hot air.

2.4 Detailed Description
(see Fig. 2-4: EM510 Detailed Block Diagram)
This section deals with the functionsof the major functional blocks.
2.4.1 Power Supply Modules
The EM510 operates either on AC or on DC.
- DC voltage: 12 to 32 VDC
- AC voltage: 100 to 240 VAC (115, 230 VAC nominal) with a frequency of 50 to 60 Hz
If both voltage sources are connected, AC supply operation is favored. If the AC supply fails, switch-
over to battery operation is effected automatically.
The mains connector is provided withtwo mains fuses (F1, F2) and an EMC filter. The mains fuses
protect the electronic circuits against overload and short circuits. The EMC filter prevents radiated
interference from leaving the equipment and also prevents picked-up and conducted interference from
entering the equipment.
The external AC voltage is fed from the mains connector to the AC/DC converter. This converts the AC
voltage into a DC voltage of 24 V, which is fed to the power supply.
The 12 to 32-VDC voltage is fed directly from the DC input to the power supply.
If the POWER switch on the front panel is on, a switch-over circuit in the power supplyconnects one of
the DC voltages.
The POWER LEDindicates whether or not power is being supplied to the power supply.
The power supply contains five DC/DC converters which provide the HF receiver module and the fans
with the required operating voltages. The following stabilized voltages are generated:
Forthe HF receiver module
+5.15 0.15 VDC / 5.5 A
Forthe fans
+8 VDC / 0.5 A
All outputs are protected against short circuit and overvoltage. Green LEDs on the power supply
indicate the presence of the DC input and supply voltages.

4065.7763.32-01.00 2.8
2.4.2 HF Receiver Module
The HF receiver module is controlled via the LAN interface X11.
The necessary signal inputs and outputs of the HF receiver module are routed via RF cables to the
connectors on the rear and front panel or are available through the opening in the rear panel.
The RF antenna signal is fed in at connectorX1 RF and then taken via RF cable to the RF input of the
HF receiver module. In the digital receiver the received signals are passed through the filters in the
preselection on to the A/D converter, and are subsequently digitally filtered and demodulated to
produce the baseband, video and AF signals. These signals can be transmitted in digital form via the
LAN interface. Together with further output signals for detailed signal analysis and monitoring they are
also made available via the following connectors:
Rear panel:
X6 VIDEO A: Analog video output A for AM and I components
X7 VIDEO B: Analog video output B for FM and Qcomponents
X12a AUDIO: Audio output analog and digital
X14 FPDP: Wideband digital interface. FPDP (Front Panel Data Port) is a platform-independent 32-
bit synchronous data flow path that allows data to be transferred at high speeds (up to 1 Gbit/s),
e.g. AF or baseband signal (I and Q) in digital form.
Front panel:
X10 AF: Phone jack (stereo socket AF_L; AF_R), AF analog headphone output (600 line and
headphones)
For the purposes of synchronization the following inputs and outputs are available on the rear panel:
X8 REF OUT: Output for internal reference signal, f = 10 MHz
X9 REF IN: Input for external reference signal, f = 10 MHz
The HF receiver modulecan use an internal frequency reference or can be set to synchronize to the
external frequency at X9 REF IN to provide even better frequency accuracy and stability.
