Multi-Measuring plug-in system MME (Experimental Device for our QSD-Serie)
This Multi-Measuring System was designed for general lab and service measurement applications.
The system consists of a basic unit and is available in different sizes.
It is available as Rack 19" module 3 HE and two smaller variants of 64 TE and 42 TE, the latter being specially suited for onsite lab and service tasks.
The basic unit contains a power supply unit and an internal bus structure (backplane) with which the module can be powered and controlled.
The measuring and testing devices available separately for this are delivered as cassette slots of various sizes (subunits) and integrated into the system.
 Desktop unit 1 (Dimensions 340mm x 360mm x 150mm)
- Desktop unit 2 (Dimensions 250mm x 360mm x 150mm)
- 19" Module HE 84 TE 3 HE
Modules:
|
MME-Start1
|
Softstart is required in every measuring system as the basic module. Power supply and fan control are integrated into this module. |
|
MME_PS1
|
Power supply unit with an output voltage up to 28 V ans a maximum current of 20 A. This power supply unit is designed as an adjustable lab power supply with adjustable voltage and current limits.
|
|
MME-Load-Mini
|
This involves a high-frequency artificial load for transmitter with 50 Ohm 0..100 MHz and a maximum power of 60 Watt. A high-frequency tab of -40dB as well as an AM demodulator output are integrated.
|
|
MME-Load-Maxi
|
This is the enhanced artificial load for transmitter with 50 Ohm 0..100 MHz and a maximum power of 120 Watt. It also contains a high-frequency tab of -40dB as well as an AM demodulator output. |
|
MME-Load-Maxi-dig
|
In addition, there is also power measurement with a display. |
|
MME-Tune1
|
Matchbox for detuning or adjusting the line impedance in the capacitive and inductive phase angle. |
|
MME_FPKPuls1
|
Pulse generator with direct interface (pulse / analog) to all QSD drivers. |
|
MME-Pickup1
|
It contains a directional coupler 5-150 MHz with tab of -30dB and a sharpness of directivity of 20dB.
|
|
MME-Pickup2
|
The directional coupler has an integrated TRU-PWR power measurement.
|
|
MME-Power-Display1
|
This module forms the display for MME-Pickup2. Together with the latter, it constitutes a reflectometer for the forward and reflected power (VSWR METER).
|
|
MME-FGen-HF1
|
High-frequency generator 10..80 MHz with adjustable power output 0..0,5 Watt at 50 Ohm. |
|
MME-Power-Rec1
|
Broadband amplifier with maximum power output 50 Watt and a frequency range of 10..35 MHz at 50 Ohm. |
|
MME-Power-Rec2
|
Second variant for the frequency range 35..80 MHz. |
|
MME-Power-Rec3
|
Broadband amplifier with maximum power output 100 Watt and a frequency range of 10..35 MHz at 50 Ohm. |
|
MME-Power-Rec4
|
Second variant for the frequency range 35..80 MHz and maximum power output 100 Watt. |
All QSD drivers, from Femto (3 Watt) to Mini (100 Watt), are available as plug-in reference drivers.
