HP 8757E Scalar Network Analyzer

Measure insertion loss, gain, return loss, SWR, and power quickly and accurately with the HP 8757E scalar network analyzer. With high-performance detectors and directional bridges, and a companion HP source and printer, this analyzer becomes the basis of a complete measurement system with superb performance. The HP 8757E features three detector inputs and two independent display channels, allowing simultaneous ratioed or non-ratioed measurement of your device's transmission and reflection characteristics. The internal plotter/printer buffer allows you to send your measurement data directly to a printer and then proceed to the next measurement. Menu-driven, direct-access softkeys simplify operation. You can order a complete 20 GHz coaxial system (the HP 8757XC), or configure your own system to 50 GHz in coax or to 110 GHz in waveguide with an appropriate HP sweeper.

System Accuracy
Insertion Loss or Gain Measurement Accuracy
    Transmission loss or gain measurements are made relative to a 
    0 dB reference point established at calibration. 

Transmission Measurement Uncertainty
		= dynamic power accuracy + mismatch uncertainty

Dynamic power accuracy is the measurement uncertainty due to the 
change in power level between calibration and the measurement. 
Mismatch uncertainty is the uncertainty due to reflections in the 
measurement setup. The frequency response errors of the source, 
detectors, bridge, and power splitter are removed via calibration. 

Transmission Measurement Uncertainty Examples 
Assumptions: 
* Measurement frequency = 10 GHz 
* DUT input/output SWR = 1.5
* Change in power after calibration <30 dB (+0 to -30 dBm range) 

Uncertainty component	HP 85037B 		HP 85025E 		HP 11664E 
			precision detector 	detector		detector
----------------------------------------------------------------------------------
Dynamic Accuracy (±dB) 	0.11 			0.40 			0.30
Mismatch (±dB) 		0.45 			0.33 			0.61
----------------------------------------------------------------------------------
Uncertainty Total (±dB) 0.56 			0.73 			0.91

Absolute Power Measurement Accuracy
	This specification is useful for determining the accuracy 
	of power measurements in dBm when using the HP 85037 series 
	precision detectors or the HP 85025 series precision detectors 
	in dc mode. 

Absolute power uncertainty = absolute power accuracy at 50 MHz
			+ frequency response + mismatch uncertainty

Absolute Power Measurement Uncertainty Examples 
Assumptions: 
* Measurement frequency = 10 GHz 
* DUT input/output SWR = 1.5 
* Measured power = 0 dBm 

Uncertainty component	HP 85037B 		HP 85025E

-------------------------------------------------------------
Absolute Power		
accuracy at 50 MHz (±dB) 	0.11 		0.40 		
Frequency response (±dB)	0.18		0.50	
Mismatch (±dB) 			0.18 		0.10 		
-------------------------------------------------------------
Uncertainty Total (±dB) 	0.47            1.00

Reflection Measurement Accuracy
	Uncertainties due to calibration error and the frequency 
	response of the source, detectors, and bridges are removed 
	via open/short averaging. The remaining uncertainties are 
	primarily the sum of directivity uncertainty, effective source 
	match uncertainty, and dynamic power accuracy. See technical 
	data sheet for further information.
