Accessory Siglent SSG3021X IQE-Plus
5 of 5 Article
SIGLENT’S SSG3000X Plus series of signal generators have a frequency range of 9 kHz to 2.1 GHz/3.2 GHz. They provide normal analog modulation such as AM, FM, and PM. They also provide pulse modulation and pulse train generator.
In addition, when used with baseband generator such as SDG6000X, they can generate IQ modulated signals(only -IQE version). With their high accuracy and pure outputs, the SSG3000X Plus series is the right choice for R&D, education, and manufacturing.

Frontal view
The Siglent SSG3000X Plus signal generators feature a clearly organized user interface and display important status and system information on the touchscreen at all times.
Rearview
Numerous ports are available for controlling and synchronizing signals. This is also where the high-stability OCXO reference module is housed (optional).
+20 dBm Output Power
Wide output range: -110 dBm ~ +20 dBm
Level accuracy: ≤ ±0.7 dB (typ.)
Level resolution: 0.01 dB
Phase Noise
Phase noise is a key indicator of signal purity Low phase noise makes it ideal for receiver sensitivity testing and digital modulation Harmonics < -30 dBc, spurious < -60 dBc, high spectral purity reduces interference to the DUT
Analog Modulation
AM / FM / PM modulation
Modulation Sources：
Internal: Shared with LF, generates sine, square, etc. Internal + External: Supports dual-tone or complex modulation External: Accepts arbitrary waveforms, modulation depth controlled by external signal level (EXT MOD INPUT)
Pulse Modulation
Pulse Modulation：
Pulse Source: Internal generator or external (PULSE IN/OUT) Pulse Types: Single, Double, Pulse Train (PT option) Pulse Parameters: Period, Width, #2 Width, Double Pulse Delay, etc.
Trigger Modes:
Auto, Manual, Bus, External Trigger, External Gated Trigger Delay, Trigger Edge (Rising/Falling), Trigger Polarity (Positive/Negative)
Pulse Train Generator
Graphical pulse sequence display with zoom function for waveform details. Freely customize positive / negative pulse width and repetition count for each pulse. Full pulse sequence editing with load/save support as *.PULSTRN files.
External IQ Modulation
IQE Models Only
Work with external IQ baseband sources (e.g. SDG6000X) Generates vector signals (32QAM, etc.) and multi-tone signals for active device linearity evaluation
Power Meter Measurement
Displays the current reading of the power meter with selectable units (dBm, dBμV, etc.)
Statistics: Average, Min, Max, Count Closed-loop control: Automatically adjusts output to maintain stable DUT power, compensating cable loss, gain, and frequency response
