Measurement Function Key Features

Fast Sweep Mode

GSP-9300 supports the fast sweep mode with sweep speed up to 307usec. Users can use the fast sweep mode to capture transient signals such as Tire-pressure monitoring system (TPMS), Bluetooth frequency hopping signals, tuned oscillator, and other interfering signals in ISM frequency band, etc.

2FSK Signal Analysis

2FSK modulation, for its features of low design cost and low electricity consumption, is widely used by RF communications applications with low power and low data transmission speed characteristics. Nowadays, 2FSK modulation technology has been applied in various products and systems such as consumer electronics, automotive electronics, RFID, auto reading electricity meter, and industrial control devices, etc. 
2FSK signal analysis measures parameters including carrier power, FSK frequency deviation, carrier frequency, and carrier frequency offset. Users can set the criterion in frequency deviation and carrier offset for fast test result determination.

ASK/FSK Signal Demodulation & Analysis

RFID and optical communications systems often use Amplitude Shift Keying (ASK). Applications such as wireless telephone, paging systems, and RFID, etc. utilize Frequency Shift Keying (FSK).
ASK/FSK demodulation and analysis measures parameters including AM depth, frequency deviation, modulation rate, carrier power, carrier frequency offset, SINAD, symbol, and waveform. Users can set AM depth, frequency deviation, carrier power and carrier offset for Pass/Fail testing result.

ASK Analyzer

AM/FM Signal Demodulation & Analysis

AM/FM Signal Analysis measures parameters including AM depth, frequency deviation, modulation rate, carrier power, carrier frequency offset and SINAD. Users can set the criterion in AM depth, frequency deviation, carrier power and carrier offset for fast test result determination.
The GSP-9300 has a convenient AM/FM demodulation function to tune into AM or FM broadcast signals and listen to the demodulated baseband signals using the ear phone out socket.

AM Analyzer

EMC Pretest Mode

EMC pretest mode is ideal for electromagnetic compatibility (EMC) test which is the preliminary stage of electronics product development. Users can identify and resolve problems at the early phase to avoid product revision after it was finalized. Hence, product development cycle and cost will be greatly reduced which is beneficial to saving cost and time for product entering the verification stage.
GSP-9300 supports -6dB EMI filter with 200/9k/120k/1M Hz bandwidth and built-in low noise amplifier. Users can apply maximum peak detector and EMI filter to conduct pre-compliance testing for electronics products. Users can activate built-in amplifier to measure feeble electromagnetic interfering signals to -150dBm/Hz in 1GHz frequency band.
EMC pretest mode collocates with near field probe or antenna to carry out conduction and radiationelectromagnetic interference (EMI) test. Additionally, near field probe and GSP-9300 tracking generator can be used to output 0dBm RF signals to test electromagnetic susceptibility (EMS) for electronics products.

EMI Pretest

Spectrogram

Spectrogram can simultaneously display power, frequency, and time. Frequency and power variation according to time changes can also be tracked. Especially, the intermittently appeared signals can be identified. Users, by using Spectrogram, can analyze the stability of signal versus time or identify the intermittently appeared interference signals in the communications system. Users can use two markers to find out the relation of power to frequency and time.

Topographic

Topographic uses color shade to show the probability distribution of signal appearance. This function allows users to directly understand the process of signal variation according to time changes that is beneficial to observe intermittent feeble signals or electromagneticinterference signals. Users can use two makers to find out the relation of power to frequency and percentage.

Gated Sweep

Radar or TDMA communications systems, via intermittently turning on/off output power, control transmission signals. In order to monitor the power spectrum during the transmission process, the Gated Sweep function can initiate measurement only when signals appear. This function is ideal for measuring burst signals such as GSM or WLAN (as shown in the example).

OCBW ( Occupied Bandwidth )

The OCBW measurement can simultaneously display OCBW, channel power and PSD. OCBW’s unit is shown by percentage. A measurement area containing bandwidth will be shown when OCBW is in use.

ACPR ( Adjacent Channel Power Ratio )

Telecommunications and broadcasting service carriers must reduce interference to the minimum. This interference is caused by power leakage to adjacent transmission channels. The ACPR measurement can examine the leakage status that is conducive to identifying interference source.

SEM ( Spectrum Emission Mask )

SEM measures out-of-channel emission which is defined by corresponding in-channel power. Users can set main channel’s parameters, out-of-channel range, and limit line, etc. SEM supports the Pass/Fail test function and lists frequency range for surpassing each out-of-channel limit. An alarm signal will be triggered if any measurement results that are not matched with SEM. GSP-9300 has the built-in SEM settings of 3GPP, WLAN 802.11b/g/n, Wimax 802.16 and self-defined communications system.

TOI ( Third Order Intercept )

Users can measure the linearity of non-linear systems and components such as receiver, low-noise amplifier and mixer by TOI which automatically tests effective carrier and measures inter-modulation sidebands.

Harmonic

Harmonic can easily measure the amplitude of fundamental frequency and as high as ten orders of harmonic frequency. This function can also measure amplitude (dBc) which is the ratio of harmonic and corresponding fundamental carrier. Total harmonic distortion (THD) can also be calculated by this function.

Time Domain Power

Users can go to zero span setting and open marker to observe burst signals when measuring burst signal in time domain is required.

Phase Jitter

The Phase Jitter function can rapidly measure phase noise produced by RF signal source’s and oscillator’s carrier deviation. This function can directly convert signal jitter to phase (rad) and time (ns).

CNR/CSO/CTB

The built-in CNR/CSO/CTB functions of GSP-9300 are ideal for measuring performance of CATV amplifier and system.

Frequency Counter

The frequency counter function is used to make accurate frequency measurements up to 1Hz resolution.

Marker Noise

The marker noise function calculates the average noise level over a bandwidth of 1Hz, referenced from the marker position.

Production Line Key Features

Shorten Warm-Up Time

GSP-9300 utilizes the patented design of high efficient heat dissipation and feedback temperature control. After the instrument is turned on, the internal instrument can rapidly maintain a stable temperature so as to provide accurate amplitude measurement and deliver the frequency measurement with 0.025ppm frequency stability.

Wake-Up Clock

Users can set up automatic wake-up time for each day of the week. By so doing, the purpose of GSP-9300 pre wake-up can be achieved. Pre wake-up is ideal for the lower temperature environment to conduct tests in the preset time.

Sequence Function

The sequence function allows users to edit a sequence formulated by a series of steps directly from the instrument. Pause and delay can be inserted in the sequence to observe the test results. There are five sets of sequence for selection. Each sequence allows editing of 20 steps. Different sequence can be interactive and support each other. This function provides automatic editing without using the PC that is very convenient for assembly lines in which execute routine test procedures.

Limit Line Function

The limit line function, based upon the preset criteria of passing the test, can be used to directly determine whether the DUT passes the test.
Test result not only can be shown on the LCD screen, but also an alarm signal output indication which is done by connecting a speaker or light device with the BNC terminal on the rear panel to facilitate the maximum yield rate of the production line.

Various Interface

GSP-9300 provides instrument control interface including LAN, RS-232, USB, and GPIB (optional).
IVI driver is also provided to support LabVIEW / CVI / LabWindows to meet the requirements of editing the automatic test software.

Options

Scalar Network Analysis

The built-in tracking generator can swiftly and easily measure frequency response of cable loss, filter bandwidth, amplifier gain, mixer conversion loss, etc. The N-dB Bandwidth function measures 3dB bandwidth of Bandpass filter. SWR bridge should be connected with tracking generator to measure the return loss of antenna or filter.

P1dB Point Measurement

All active components have linear dynamic range for power output. Once output power reaches the maximum level, active component will enter the non-linear saturated area of P1dB point and cease amplifying signal intensity as well as produce harmonic distortion. It is very useful for P1dB point measurement in active components such as low noise amplifier, mixer and active filter.
The GSP-9300 tracking generator supports 50dB power sweep range; output power from 0dBm to -50dBm; frequency range from 100kHz to 3GHz.
