The GSP-827 is designed with the features as follows. — Synthesized-based design covering the frequency from 9kHz to 2.7GHz. — Low noise design: -140dBm/Hz noise floor. — 4.5kg light weight and compact size. — 100 traces and setup memories. — ACPR, OCBW, CHBW of power measurement. — 11 ranges of external reference clock (64k~19.2M). — 10 Markers with Peak, Peak Track, ΔMarker, Marker to Center functions. — External and Video Level Trigger with single and continuous modes. — Limit Line and Pass/Fail functions for quickly qualification test. — Spilt Windows extend the measurement flexibility. — Trace functions including Peak Hold, Average and Freeze. — Optional Tracking Generator provides frequency response measurement in one sweep. — Optional filters and Quasi- Peak detection provide EMI test. — GPIB and RS232 interface for ATE applications. — AC/DC dual modes power supply and Battery Operations. The fully synthesized-based and low noise designs offer the high RF performance in measurement. The plentiful measurement functions like 10 markers, traces, power measurement, limit line, dual display and trigger make measurement more easily and quickly. The 100 memories, real time calendar and battery operation realize the true portability. 11 ranges of external reference clock offer the synchronization capability to many telecom standards. The optional Tracking Generator offers the frequency response test with the same frequency band. The GPIB and RS232 interfaces allow the connection between the unit and PC. Users can develop their own applications software. DC 12V power supply allows user to carry this unit to drive around for frequency monitoring. Chargeable battery pack can support the operation without power cord for 4 hours. With the carrying case, this unit is easy to carry and operate in the filed service. 9k and 120k EMI filter and quasi-peak detector can perform the EMC test. AM/FM Demodulation provides the demodulated outputs through both headphone and speaker. Kit sets of connector adaptor offers the convenience under different measurement conditions. This unit offers the right combination of highly RF performance, plentiful function, easily operated user interface and complete options to facilitate measurement in a wide range of application in laboratory as well as in field service usage. This is another example of our dedication to engineering excellence.
