Microwave Peak Power Meter 微波峰值功率计
- 30 MHz to 40 GHz Frequency Range
- Graph Mode for Plot of Pulse Profile
- Full GPIB Control
Specifications
- Frequency Range: 30 MHz to 40 GHz depending on detectors (see PEAK POWER
SENSOR specifications)
- Power Range
* Pulse: -20 dBm to +20 dBm
* CW: -40 dBm to +20 dBm
(See sensor specifications)
- Time Base Range: 1.2 ns/div to 20 ms/div (12 ns to 200 ms time window),
using either the Data Entry Keyboard or the Control Knob.
* Resolution: 0.1 ns
- Trigger Delay Range: 0 to 200 ms using either the Data Entry Keyboard or
the Control Knob.
* Resolution: 0.1 ns
- Triggering Modes
* Internal: -10 dBm to +16 dBm
* External (BNC): TTL levels, Maximum PRF 1 MHz
- Markers: Up to 4 markers/channel plus a Reference Power Level cursor
- Graph Display Mode: Plots the outline of the detected pulse on the LCD
display
- Output Channels
* 8501: Single Channel
* 8502: Dual Channel
- Auxiliary Outputs/Inputs (BNC)
* Monitor: Provides a voltage proportional to the detected RF
envelope. Risetime is typically 20 ns, output impedance is
nominally 50W
* Analog Output: Provides a voltage proportional to detected power.
Scale Factor is 100 mV/dB
* Trigger Input: TTL
* RF Blanking: TTL open collector low during zeroing. Used to control
power source
* Voltage Proportional to Freq (V / GHz): Allows direct entry of frequency
from RF power sources equipped with a VaF output
- GPIB Interface
