The manual for the Model 2005B RF Signal Generator provides detailed instructions on setup, operation, and troubleshooting, including how to connect the device, adjust frequency and modulation settings, and perform maintenance tasks such as fuse replacement. It also covers the use of the generator for both internal and external modulation, unmodulated carrier testing, and crystal oscillator output, with specific guidance on calibration and safety precautions.
Manual Overview
The Bk Manual for the Model 2005B RF Signal Generator provides detailed instructions on operation, troubleshooting, and maintenance. The generator covers a frequency range from 100KHz to 150MHz, with up to 450MHz on third harmonics, and offers both internal and external modulation options. Troubleshooting focuses on ensuring correct connections and settings, such as using a blocking capacitor to prevent detuning and ensuring no high DC voltage is present when connecting directly to input circuits. Calibration involves using the harmonics of an internal crystal oscillator and an external receiver for precise frequency adjustments. Maintenance includes case removal and fuse replacement, with specific instructions for accessing internal components safely. The manual emphasizes caution due to the presence of line voltage when the unit is open. Error diagnostics are primarily indicated by the pilot light; a blown fuse will extinguish the light, necessitating investigation and replacement with specified fuses.
Quick Issues Covered

– Select the desired frequency range using the FREQ RANGE switch and adjust the frequency dial knob.
2. Connections:
– Connect RF leads to the input of the circuit under test.
– Use a resistor in series for receiver antenna input or connect leads to a coil for rod antennas.
– Use a small capacitor for RF and IF amplifier circuits to prevent detuning.
3. Modulated Carrier, Internal Source:
– Set the mode switch to INT. MOD.
– Tune the receiver to the generator frequency to hear an audio tone.
– Keep the RF signal level low to avoid overloading.
4. Modulated Carrier, External Source:
– Set the mode switch to EXT. MOD.
– Connect an external audio generator to the INPUT.
– Use frequencies up to 15KHz for modulation at RF above 3MHz.
5. Unmodulated Carrier:
– Set the mode switch to EXT. MOD with no input connection.
– Use the RF signal for testing with a beat oscillator or circuits not requiring modulation.
6. Crystal Oscillator Output:
– Set mode switch to XTAL and insert a crystal in the XTAL socket.
– Set RF output switch to LOW and adjust frequency settings as needed.
7. AF Output 1KHz:
– Set mode switch to INT. MOD and adjust frequency settings.
– Connect leads from OUTPUT to the test circuit.
8. Oscillator Frequency Calibration:
– Use the harmonics of the internal crystal oscillator and an external receiver for calibration.
– Set the mode switch to XTAL and insert a standard frequency crystal.
