AC/DC/Battery 3-way power operation Compact size, 330(W) x170 (H)x340 (D) mm Light weight of 4.8kg without options Optional Tracking Generator Optional Preamplifier (NEW!) Optional RBW:300Hz, 9k,120k

7 Low Noise Floor: Good for small signal measurement Features -117dBm

8 Features Friendly User Interface High resolution and TFT color LCD provides the clear and nice measurement result quality.

9 Features Entry Data Area: The signal trace is no more overlaid by the entry data on LCD. Center :2.400GHz Center :2.400GHz

10 Status Information Presented by ICONS: To indicate the working status of Spectrum Analyzer. Trace identification and its working mode Features :Trace A is working under either one of Clear and Write, Average, View, Peak hold modes. Indication of signal is measured under the specific settings. :The amplitude is offset because 75 ohm input resistance, correction table on, or extra gain / loss is employed. :One of RBW, VBW or Sweep Time is in the Manual mode which will cause the signal looked abnormal, or slow the sweep.

11 Status Information Presented by ICONS: Features To indicate the current working status of Spectrum Analyzer. Cases of SA is worked under the specific modes. :Peak (marker) Track mode is selected, the peak marker will repeat Peak search + Marker to Center functions. :Sequence is ON and the SA is automated. :The external reference signal is connected and works. :The TG normalization is on. :The Trigger function is set on external trigger source :The DC 12V power battery indicator.

12 Autoset Function: Features Signal is automatically measured and located at the display center. The amplitude and span can be assigned and functioned in manual mode.

13 Features Sequence Function: Front panel operations can be automated with built-in in Sequence programming functions. Performing automation without PC connected.

14 A, B, C Traces : To distinguish different signals Features

15 Features Split Windows: Two test setups can work simultaneously.

16 Limit Line Editing to define the test zone Features

17 3 criteria are allowed for Pass/Fail test : Entire Curve, Maximum or Minimum in defined zone Features

18 5 pairs of Marker-ΔMarker with Marker Table Features

19 10 Markers with Marker Table Features

20 Features ACPR Measurement with Color bars and large Characters

21 Features ACPR (Adjacent Channel Power Ratio) Measurement: Measure of adj. channel leakage related to Main Ch. P ch LACPR1= UACPR1= LACPR2= P L1 P ch P u1 P ch P L2 P ch UACPR2= P u2 P ch P L2 P L1 P U1 P U2 All measurement all resulted in db. Greater db number means greater (better) rejection ratio between channels.

22 ACPR Measurement: Parameter Definition Adj Ch BW 2 Adj Ch Adj Ch Adj Ch BW 1 Ch BW BW 1 BW 2 P ch Features Must Parameters: CH BW; Adj CH BW 1; Adj CH Offset 1; Adj CH BW 2*; Adj CH Offset 2*; P L1 P U1 Parameters of Upper and Lower adjacent channels are symmetrical to the main channel. P L2 P U2 Adj Ch Offset Adj Ch Offset Adj Ch 1 1 Adj Ch Offset2 Offset2 *: Are must only the 2nd adjacent channel measurements are demanded.

23 ACPR Measurement Review Features

24 Features OCBW (Occupied BW) Measurement

25 Features OCBW Measurement : Measure of BW which takes the specified percentage BW in the Channel CH BW Must Parameters: CH BW; OCBW %; OCBW Lesser OCBW number at the specified % means more concentrated power distribution in the channel.

26 N-dB BW Measurement Features

27 Features USB Interface : Link to Memory Stick, PC, Printer

28 Features VGA Direct output : Convenient for Remote Monitoring EMI Lab Chamber

29 Features VGA Direct output : Convenient for Demonstration Training, School

30 Pre-amplifier: GAP-801/802 GAP-801 DC Power for GAP-801/802 Options Preamplifier with 10dB(Typical, 9kHz ~ 6GHz) GAP-802 Preamplifier with 20dB(Typical, 9kHz ~ 3GHz) 30

31 Options The most efficient EMI debugging & Pretest tool: GSP + GAP-801 /802+ GKT-006
