# Aim-TTi PSA3605 3.6 GHz Portable RF Spectrum Analyzer # Aim-TTi PSA3605 3.6 GHz Portable RF Spectrum Analyzer ## Key Features At A Glance - Frequency range from 10 MHz to 3.6 GHz or 6.0 GHz across the two PSA Series 5 models - Displayed noise floor better than -120 dBm at -40 dBm ref level and 10 kHz RBW (better than -160 dBm/Hz) - Resolution bandwidths from 300 Hz to 10 MHz in a 1:3:10 sequence, or Auto RBW - 4.3-inch colour TFT resistive touchscreen with a three-row hierarchical menu system - Li-ion battery gives more than 3 hours continuous operation; recharges in under 3 hours - USB host and USB device interfaces plus trigger in/out for Flash-drive storage and PC file transfer - True handheld size: 192 x 92 x 49 mm at around 560 g (20 oz) - Optional U02 firmware adds limit patterns, data logging, CP/ACPR/OBW measurements, Scan Mode and demodulation The PSA Series 5 is a true handheld RF spectrum analyzer from Aim-TTi, offered as the PSA3605 covering 10 MHz to 3.6 GHz and the PSA6005 covering 10 MHz to 6.0 GHz. Described as delivering bench-top performance with handheld convenience, it is the latest and highest-performance handheld spectrum analyzer in the line, complementing the existing PSA Series 2 with a significantly expanded feature set and frequency capability up to 6 GHz, in a package small and light enough to fit comfortably in the hand. The PSA Series 5 is built for use both on the bench and in the field. A removable screen protector and sun-shield, together with rubberised buffers top and bottom, support use in the field, while the supplied AC line adaptor powers the instrument and charges it for continuous bench-top operation. Its low cost is positioned to let every engineer have access to a spectrum analyzer whenever one is needed, and the optional PSA-ANT2 telescopic antenna suits general-purpose applications where absolute measurements of field strength are not required. ValueTronics keeps its inventory in a 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, stocking and holding the equipment it sells on its own shelves. ## Compare Other Models in This Series The PSA Series 5 comprises two true handheld RF spectrum analyzers that share a common feature set and differ principally in upper frequency limit: the PSA3605 reaches 3.6 GHz and the PSA6005 reaches 6.0 GHz. Both deliver what Aim-TTi describes as bench-top performance with handheld convenience, combining a 4.3-inch colour touchscreen, 1.8 GB of internal storage, USB host and device connectivity, and Li-ion battery operation in a package that fits in the hand at around 560 grams. Each model can also be ordered in a USC version — the PSA3605USC and PSA6005USC — which arrives with the U02 firmware upgrade pre-installed plus the telescopic antenna, vehicle charger and travel case supplied in a fitted case. Option U02 is otherwise a user-installable firmware upgrade available for either base model, adding limit patterns, data logging, automatic CP/ACPR/OBW measurements, Scan Mode and waveform demodulation. Each new model listed below is its own dedicated product page with condition-matched pricing. Select the model whose frequency coverage and options match your application, then choose the new listing that fits your budget and timeline. The two models differ in their frequency span and related sweep limits. The PSA3605 covers 10 MHz to 3600 MHz with a maximum span of 3590 MHz, while the PSA6005 covers 10 MHz to 6000 MHz with a maximum span of 5990 MHz. Both share a minimum span of 27 kHz (or zero span with demodulation), 100 Hz setting resolution and the same reference frequency accuracy of better than ±1 ppm at 20 °C. Phase-noise figures are specified at several carrier frequencies, with the 6 GHz carrier figures applicable to the PSA6005 only. Aside from frequency coverage, the models are functionally identical — the same amplitude range, marker system, storage, connectivity and Option U02 capabilities apply to both. The comparison table that follows lists the per-model frequency and span values side by side.
