Channel Power / Occupied Bandwidth An important characteristic of a modulated signal is its occupied bandwidth. In a radio communications system for instance the occupied bandwidth must be limited to enable distortion-free transmission in adjacent channels.
Adjacent Channel Power Ratio ( ACPR ) 3G WCDMA Base station signal Adjacent Channel Power Ratio (ACPR) is ratio between the total power of adjacent channel (inter-modulation signal) to the main channel's power (useful signal).
Spectrum Emission Mask ( SEM ) Spectrum Emission Mask Predefined masks for 3GPP 802.11a/b/g/n / 802.
Harmonic Distortion < -50dBc The total harmonic distortion, or THD, of a signal is a measurement of the harmonic distortion present and is defined as the ratio of the sum of the powers of all harmonic components to the power of the fundamental frequency.
Third-Order Intercept ( TOI ) In telecommunications, a third-order intercept point ( IP3 or TOI ) is a measure for weakly nonlinear systems and devices, for example receivers, linear amplifiers and mixers.
Phase Jitter Phase noise is the result of small random fluctuations or uncertainty in the phase of an electronic signal. RF engineers speak of the phase noise of an oscillator, whereas digital system engineers work with the jitter of a clock.
CNR / CSO / CTB • For CATV amplifier & system testing CNR CSO CTB 17
P1dB Compression Point Mixer Low noise amplifier Power amplifier 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.
N-dB Bandwidth The 3dB point is the point at which the signal has been attenuated by 3dB ( in a Bandpass filter). This is generally considered the point for determining the filter's bandwidth. The bandwidth is defined as the difference between the upper and lower 3dB points.
AM / FM Demodulation & Analysis Measure the AM/FM Radio Tuner & Ham Radio Device AM/FM AF-demodulation with headphone Useful for interference analysis
ASK / FSK Demodulation & Analysis 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.

Limit Line & Pass/Fail Test Pass/Fail Inspection Test performs the test result judgment with inspection criteria pre-defined by user. The procedure is as follows: (a) Create Limit lines to set the inspection zone. (b) Select the Pass Criterion. (c) Execute the Pass/Fail test.
Wake-Up Clock Wake-Up Clock automatically turns on the power of GSP-9300 spectrum analyzer at user’s pre-set time, which can be used to warm up the instrument in advance before the measurements are made to ensure the accuracy of measurement results, particularly in the low ambient temperature circumstance. Automatic Turns on GSP-9300 every working day Time is Money $$$.
Sequence The sequence function allows users to edit a sequence formulated by a series of steps directly from the instrument. This function provides automatic editing without using the PC that is very convenient for assembly lines in which execute routine test procedures.
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).
Frequency Counter & Marker Noise The frequency counter function is used to make accurate frequency measurements up to 1Hz resolution. The marker noise function calculates the average noise level over a bandwidth of 1Hz, referenced from the marker position.
