8757D Scalar Network Analyzers
Measure insertion loss, gain, return loss, SWR, and power quickly and
accurately with the 8757D scalar network analyzer. With high-perfor-
mance detectors and directional bridges, and a companion source and
digital plotter, the 8757D is the basis of a complete measurement
system with superb performance.
The 8757D features three detector inputs and two independent
display channels, allowing simultaneous ratioed or non-ratioed
measurement of your device’s transmission and reflection charac-
teristics, 75 dB dynamic range (+20 to –55 dBm) for measuring
high-rejection devices, and a choice between ac (square wave modu-
lated) or dc detection techniques. The internal plotter/printer
buffer allows you to send your measurement data directly to a
plotter and then proceed to the next measurement, typically in less
than five seconds. The 8757D includes a user-friendly interface, and
menu-driven, direct-access softkeys, which simplify its operation.
It offers limit testing, external disk save/recall, and a color dis-
play. Limit testing reduces test time by letting the analyzer make
quick and objective pass/fail decisions. External disk save/recall
allows your measurement state to be preconfigured by an engineer
or skilled specialist and then automatically recalled by production
technicians. The result is reduced set-up time and greater test
integrity at each production station. The precision color display sim-
plifies the separation of measurement information while providing
a pleasant display for the technician.
Increase Absolute Power Measurement Accuracy
For near power meter measurement accuracy, configure a system
that includes the 8757D Option 002 and the 85037 series precision
detectors. Option 002 on the 8757D adds an internal power calibra-
tor used to characterize the 85037 series detectors’ accuracy versus
power. In addition, each 85037 series precision detector incorporates
a dual-diode detector to improve power measurement accuracy when
harmonics are present, plus internal frequency correction factors,
read by the 8757D, for more accurate power versus frequency
measurements. The result is a system optimized for swept absolute
power measurements.
