HP 5348A 26.5 GHz Microwave Counter/Power Meter

The HP 5348A counter/power meter offers the convenience of a single instrument that makes frequency and power measurements with accuracy and resolution comparable to stand-alone instruments. As a true power meter, the HP 5348A offers excellent dynamic range, linearity, and accuracy. It uses the same proven power sensors as HP's standalone power meters. The high performance frequency counter measures frequency from 10 Hz to 26.5 GHz.

With only five function keys, the HP 5348A is especially easy to use. Its rugged, lightweight package, along with an optional internal battery that provides up to two hours of cordless measurements, makes the HP 5348A ideal for taking portable measurements.

  3 dBm, 500 MHz to 12.4 GHz
  4 dBm, 12.4 GHz to 20.0 GHz
  5 dBm, 20.0 GHz to 26.5 GHz

Input 2

Frequency Range: 10 Hz - 525 MHz

Sensitivity: 25 mV rms (15 mV rms typical)

Impedance: 1 Mohm nominal shunted by <70 pF (10 Hz to 80 MHz)
  or 50 ohm nomimnal (10 MHz to 525 MHz)

Damage Level: 50 ohm or 1 Mohm
              dc - 5 kHz: 250V (dc + ac peak)
	       >5 KHz: 5.5V rms (+28 dBm) + 1.25 x 10^6V rms/FREQ

Accuracy: +/-1 LSD ±[(1.4 x Trigger Error/Gate Time)±Time 
  Base Error] x frequency

Resolution: 1 Hz or 10 kHz, selectable



Automatic Amplitude Discrimination 

Automatically measures the largest of all signals present, provided 
that signal is >6 dB (typical) above any signal within 500 MHz; 
>20 dB (typical) above any signal within 500 MHz to 26.5 GHz.

Tracking Speed
  Resolution = 1 Hz, Speed = 1 MHz/sec
  Resolution = 10 kHz, Speed = 1 GHz/sec

Acquisition Time
  Resolution = 1 Hz, Time = <125 ms
  Resolution = 10 kHz, Time = <60 ms

Maximum Deviation
  20 MHz p-p, Automatic mode
  60 MHz p-p, Manual mode (via HP-IB only)

Maximum FM Rate: 10 MHz

AM Tolerance: Any modulation index provided the minimum signal level 
  is not less than the sensitivity specification.



Power Meter Specifications

Frequency Range:  0 MHz to 26.5 GHz, sensor dependent

Power Range:  -70 to +20 dBm (100 pW to 100 mW), sensor dependent

Dynamic Range: 50 dB in 10 dB steps

Resolution: 0.01 dB in logarithmic mode, 0.1% of full scale in linear mode.

Auto Filter: The meter automatically selects the required number of 
  averages for the selected range.

Accuracy
  Instrumentation: ±0.02 dB or ±5%; 
  
  Zero Set (digital settability of zero): ±5% of full scale 
    on most sensitive range. Decrease percentage by a factor of 10 for 
    each higher range, ±1 display count.
