|Hewlett Packard 83522A|
The Model 83522A is an RF plug-in which has been designed for use with the Model 8350A Sweep Oscillator. The Model 83522A covers the frequency range of 0.01 to 2.4 GHz. A YIG oscillator is used as the tunable RF frequency source and a fixed 3.8 GHz oscillator is mixed with the YIG oscillator to generate a 0.01 to 2.4 GHz RF output. Model 83522A front panel functional controls, pushbuttons, and the Rotary Pulse Generator (RPG), are monitored by the Model 8350A via the RF plug-in interface circuits. The Model 8350A generates a tuning voltage ramp according to the mode of operation (CW, START/STOP, CF/AF). This voltage ramp is scaled and offset by the Model 83522A to provide a voltage ramp which is proportional to the YIG oscillator frequency in the Model 83 522A. The Model 83522A then converts the tuning ramp voltage to a current which drives the YIG oscillator tuning coil. The Model 83522A offers a maximum leveled RF output power of +13 dBm. Internal (INT), External (EXT), and Power Meter (MTR) leveling is available as selected by the front panel pushbuttons. A front panel EXT/MTR ALC input connector and gain control (CAL) are provided to use with an external leveling loop. A front panel LED indicates when the RF output becomes unleveled. The RF output level is controlled by the Model 83522A RPG, the Model 8350A data entry controls (keypad and step keys), or through HP-IB control via the Model 8350A.
