Installation / Setup

The source provides detailed information on the setup and installation of the RF demodulator probes. The HF-Demodulator-Tastkopf 241.2116 and the LIN/LOG-Demodulator 241.1910 have specific connectors: a BNC connector and a 5-pin connector, respectively. The probes are recommended for measuring RF voltages with minimal loading on the test point, and they feature exchangeable probe tips for a wide voltage range.

For setup, the probe tips can be attached to an M-2.6 thread at the probe’s front end. The grounding connection is made using a grounding cable that screws into an M-2 thread on the probe body. At higher frequencies, a thin metal strip is recommended for grounding, which should be clamped under the probe’s grounding sleeve and connected to a ground-carrying circuit part.

When using the BNC adapter 241.1110.02, the probe can be used as a through-probe by inserting the adapter into the line and the probe into the spring sleeve. For measuring voltages above 5 V, the probe should be used with the appropriate slip-on attenuator and reducing sleeve.

The components of the probe can be accessed by loosening the M-2 screw next to the cable entry sleeve and removing the housing. However, defective slip-on attenuators cannot be repaired.

Operation

The manual provides information on the operation and basic usage steps for the RF demodulator probe and the LIN/LOG RF diode probe. It describes the selection of probe tips, the establishment of ground connections, and the use of a BNC adapter for measurements. The probe tips can be screwed or plugged onto the probe, and different tips are recommended for different frequency ranges. Ground connections should be made using a ground cable or a thin metal strip for higher frequencies. The BNC adapter allows the probe to be used as a through-head, and for voltages above 5 volts, the probe should be used with an appropriate attenuator and reducer sleeve.

Installation / Setup

The setup of the RC-Generator Type SRM BN 4085 involves adjusting the device to the appropriate mains voltage, which is preset to 220V at the factory. To change to other voltages (115, 125, or 235 V), the device must be removed from its casing by loosening screws on the front panel edges. The appropriate contact spring pair on the voltage selector must be bridged with a suitable fuse. For 235V, the 600-mA fuse used for 220V is suitable, while a 1.25-A fuse is required for 115V and 125V. After reassembly, the device is connected to the mains and switched on using the toggle switch above the mains cable entry. A small glow lamp above the switch indicates the power state. The generator is ready for operation after a warm-up period of about one minute, with optimal frequency stability achieved after approximately 15 minutes. The mains voltage can deviate by ±10% from the nominal value without significantly affecting the generator’s function, but prolonged over or under-voltage should be avoided to extend tube life. For under-voltage situations, using a transformer is recommended.

Operation

The manual provides detailed steps for the basic usage and operation of the RC-Generator Type SRM BN 4085.

1. Setting the Mains Voltage and Switching On: The device is initially set to 220V. To adjust it to other voltages (115, 125, or 235 V), the screws on the left and right edges of the front panel must be loosened, the device removed from its case, and the appropriate contact spring pair on the voltage selector must be bridged with a suitable fuse. For 235 V, the 600-mA fuse used for 220V is suitable. For 115V and 125V, a 1.25-A fuse is required. After setting, the device is reassembled, connected to the mains, and switched on using the toggle switch above the power cable entry. A small neon lamp above the mains switch indicates the on state. The generator is ready after a warm-up period of about one minute, and the specified frequency stability is reached after about fifteen minutes.

2. Frequency Setting: The desired frequency is set using the control knob below the frequency scale and the range switch on the left. For example, to set a frequency of 1000 Hz, the scale pointer should be set to 10, and the range switch to 300…3k.

3. Output Voltage Regulation: The output voltage for both outputs is regulated using the knob to the right of the frequency scale. Turning the knob to the right increases the output voltage, indicated by the amplitude arrow above the control knob.

4. Outputs and Connection Cables: Each of the two outputs, Output I and Output II, has two output sockets: one coaxial socket for 13-mm plugs and one telephone socket for 4-mm plugs. The outer conductors of the coaxial sockets and the (middle) 4-mm telephone socket marked with a ground symbol are grounded (SRM housing). If the connection between the RC generator and the consumer is to be made via a shielded cable, the cable must be equipped with a 13-mm plug on the generator side.

5. Output I: The no-load voltage of this output is a maximum of 1 V and can be continuously regulated down to about 20 mV. The distortion factor of the output voltage is independent of the size of the external resistance. The same applies to the frequency response, provided the reactive component of the external resistance is above about 10kΩ. The consumer can have an input capacitance of up to 1000 pF in the audio frequency range (f < 15 kHz) without deteriorating the specified frequency response (< +5%).

6. Output II: The no-load output voltage at this output is a maximum of 30 V, with continuous regulation down to about 0.5V. The distortion factor depends on the load or output power. For example, with a 600Ω load and 0.5W output power, it can be up to 10%. For a load of 3kΩ, it is < 1% for f < 100 kHz and 100 kHz. With an external resistance > 3kΩ, an output power of about 0.3 W is achieved. The output voltage is frequency-dependent. For external resistances Ra = 3kΩ, the
