The Tektronix SG505 is a ultra-low distortion oscillator plug-in for the TM500 system.
Option 01 adds an intermodulation test signal function.
Option 02 adds a fully balanced output to +28 dBm and selectable source impedance with corresponding changes to the front panel connections. It also includes Option 01.
Key Specifications
| Frequency range | 10 Hz to 100 kHz nom. (typ. 9 Hz to 110 kHz) in four overlapping ranges |
|---|---|
| Frequency accuracy | 3% of dial reading |
| Output level | +10 dBm to -60 dBm into 600 Ω in eight 10 dB steps, plus variable control +2.2 dB to -10 dB from calibrated position |
| Output impedance | 600 Ω |
| Distortion | < 0.0008% (-102 dB) from 20 Hz to 20 kHz |
| Sync output | 200 mVRMS sine to 20 kHz, at least 120 mV @ 100 kHz; 1 kΩ source impedance |
| Topology | State-variable oscillator with N-FET (151-1021-00) based AGC. Range switches change capacitors and AGC time constants, main dial changes integrator resistor. Oscillator built from NE5534 amplifiers. |
