HP / Agilent 436A RF / Microwave 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
