• 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
