Boonton 4400A

The Boonton Model 4400A is the instrument of choice for viewing and analyzing RF power in the time domain.

Whether you are analyzing radar, pulse bursts, GSM or TDMA wireless signals, broadcast TV and radio transmitters, or any RF signal in which the power versus- time relationship must be accurately measured and recorded, the Model 4400A is the instrument for you.

• 
  >60-dB dynamic range
• 
  Frequency range: 30 MHz to 40 GHz
• 
  1-GHz NIST Traceable Calibrator
• 
  Color VGA display
• 
  1-Msa/sec. Sampling rate
• 
  14 automatic measurements
• 
  Parallel printer port
• 
  PC-compatible 1.44-MB floppy

Fast display updates and GPIB measurements save you time and gather data faster than ever before. The PC-compatible 1.44- MB floppy drive can store data such as front panel setups and trace waveforms, and you can print or plot the display to disk for later printing or to import into your documents.

Flexible triggering, greater than 60-dB dynamic range (sensor dependent) without any range switching, channel math on
active and reference (saved) traces, and Boonton’s wide selection of Peak Power Sensors round out the Model 4400A’s industry-leading capabilities.

THE MODEL 4400A IS THE LEADER IN PULSE MEASUREMENTS

The Model 4400A provides power versus-time waveform analysis of repetitive RF signals. Applications include AM, radar,
TDMA, and GSM, as well as RF amplifier linearity testing. The time base extends to 10 nanoseconds per division with internal and external triggering. The logarithmic power display permits the entire dynamic range of more than 60 dB to be seen at the same time.

Convenient scale and centering controls allow vertical expansion of any portion of the display. A linear display scale is also provided covering power levels from nanowatts to megawatts. Two adjustable markers can read the power at any point across the waveform. In addition, the markers can be used to define a region on the waveform in which maximum power (peak hold), minimum power, long-term average power, and peak-to-average ration are measured.

This function is especially useful for characterizing the power level over a portion of the top of a pulse, such as top-level power. Two adjustable reference lines can be used with the markers to identify and measure particular power levels.

The reference lines also have the ability to automatically track the following:

• 
  Markers
• 
  Top/Bottom Power
• 
  Distal/Mesial Power
• 
  Distal/Proximal Power

An Automeasure function measures and calculates 14 common parameters of a pulse waveform and makes them available at all times in a both a summary text table and individually as a user-defined display parameter. The 14 Automeasure functions are:

*
Peak Power
  *Pulse Power   *
Average Power
*Overshoot
*Risetime
*Falltime
*Top Amplitude   *Bottom Amplitude
   *Pulse Width
*Pulse Period 
*Duty Cycle
*Offtime 
*Delay
