Dear Sir,


We  are planing to purchase refurbished model of E4406A VSA(7MHz to 4GHz) Transmitter Tester to perform following measurement.


We need to check the Error Vector Magnitude and constellation diagram of following Modulation techniques.

  • 2GFSK Signal
  • OQPSK Signal

I have following queries regarding that.

  • Can we directly measure the EVM and constellation diagram on E4406A VSA?
  • Do we compulsory need to purchase 89600 VSA Software to measure EVM and constellation diagram of above modulation techniques?

Request you to guide me further regarding this.


Thanks and Regards,

Sagar Mistry
