SA44B Time Based ERROR Improvement

[Bhargav Patel]

Hello,

We are performing the Conductive Transmitter Frequency Offset test with a SA44B Spectrum analyzer at 434MHz.In which we required frequency offset measurement accuracy around +/-10 Hz or +/-20 Hz.

As per Signal Hound SA44B, frequency accuracy with an internal reference is +/- 1 ppm. This means at 434 MHz, accuracy is +/- 434 Hz.

We purchase GPSDO clock(10MHz) to used as EXt Ref Clock to improve the frequency offset measurement results. Still, It shows the DUT Offset is + 160Hz, Previously without GPSDO it is + 434Hz. We have measured the same DUT with Spectrum Analyzer in which offset is +18Hz

SA44B Measurement setting:
Center Frequency:434.2125MHz
Span: 3KHz
RBW: 100Hz
VBW: 300Hz

It is possible to achieve +/- 20 Hz frequency offset measurement accuracy in Signal Hound?
