Requires 8480 series Power Sensor and Cable
HP 436A Power Meter
==========================================
Thermocouple Power Meter
General purpose digital power meter intended for manual and automatic RF and microwave power measurements
Compatible with the entire series of 8480 power sensors
Measures either absolute or relative power
Displays absolute power in either watts or dBm, while relative power is displayed in dB
Specifications
Frequency Range: 100kHz to 50GHz and 75 to 110GHz (depending on power sensor used)
Power Range: -70dBm to +44dBm (100pW to 25W)(sensor dependent)
Cal Factor: 16-position switch normalizes meter reading to account for calibration factor. Range 85% to 100& in 1% steps
Cal Adj: Front-panel adjustment provides capability to adjust gain in meter to match power sensor in use
Recorder Output: Proportional to indicated power with 1 volt corresponding to full scale and 0.316 volts to -5dB; 1 kohm output impedance, BNC connector
RF Blanking: Open collector TTL; low corresponds to blanking when auto-zero mode is engaged
Display: Digital display with four digits. 20% over-range capability on all ranges. Analog meter: uncalibrated peaking meter to see fast changes
