I want to know about Zigbee specification.
But I can't find the specification about Symbol clock error, EVM Offset All (PSDU , SHR), Phase error and LO Leakage.
Please let me know about those specification
ZigBee has limited specs compared to some wireless standards. The specs you need to meet are defined in 802.15.4g-2012. Section 18 is the PHY specification and section 18.3.4 in particular is for O-QPSK PHY RF requirements.
Of course you also need to meet local regulatory emissions, but for the most part ZigBee is not closely specified and has very limited interoperability compared to other wireless technologies like WiFi, BT, or cellular.
