Up for grabs is an excellent condition GW Instek GSP-9330 Spectrum Analyzer.

I also have this listed on feeBay: https://www.ebay.com/itm/167945694327
Would prefer to sell here, and can sell for a better price without the stupid fees.

Mostly interested in a cash sale, but open to full or partial trades. I could use a nice VNA calibration kit or two (minimum up to 8.5 or 9 GHz). Still looking for a DMM7510 (no projects unless the trade value reflects it).

Thanks,
Josh





Info from the manufacturer:
The GSP-9330, a high test speed spectrum analyzer with 3.25 GHz, provides the fastest 204 μs sweep speed. Users, via high speed sweep time, can easily handle and analyze modulation signals.  The keys to handling modulated signals are fast sweep time and signal demodulation functions.  In addition to the analog AM/FM demodulation and analysis function, GSP-9330 also provides digital signal ASK/FSK, and 2FSK demodulation and analysis capabilities. Nowadays, EMC issues are very crucial to product's design processes. Therefore, GSP-9330 has incorporated the EMC pretest solution to facilitate EMC tests.  The simple and easy EMC pretest procedures from GSP-9330 can tremendously shorten users' product launch timeline.

Features
- Frequency Range: 9kHz ~ 3.25GHz
- 0.025ppm Frequency Stability and 1ppm aging Rate
- RBW: 1Hz ~ 1MHz (3dB), 6dB EMI Filter: 200Hz, 9kHz, 120kHz, 1MHz
- Fastest sweep time: 204us
- Sensitivity: -149 dBm/Hz (@PreAmp on)
- Built-in Preamplifier, 50dB Attenuator, and Sequence Function
- Built-in EMC pretest function, Quasi-Peak/Average EMI detect mode
- Built-in 2FSK Analysis, AM/FM/ASK/FSK Demodulation & Analysis
- Built-in P1dB point, Harmonic, CHPW, OCBW, ACPR, SEM, TOI, CNR, CTB, CSO, N-dB bandwidth, Noise - Marker, Frequency Counter, TDP, Gated Sweep
- Built-in Spectrogram, Topographic and Split-Window Display Modes
- Remote control EMI measurement software: SpectrumShot
- Remote Control Interface: LAN, USB, RS-232

GSP-9330 can meet customers’ EMC pretest requirements on the product development and verification stages. Users can detect and resolve problems at the early product development stage that can save time and money for product development and verification fee.  As a result, users can expedite the process of products launch.  GSP-9330 has the built-in EMI dedicated 200/9 k/120 k/1 MHz filter, 20 dB low noise amplifier and Quasi-Peak/Average detection mode to conduct radiation and conduction tests after collocating with the probe set.

Anybody have a DMM7510 or a nice SMU to trade?
