• 1MHz to 1300MHz frequency range
• U01 Firmware upgrade
• 4.3 inch LCD touchscreen display
• 1.8 GB of internal memory
• USB host interface for removable USB Flash drives

A lightweight and truly handheld instrument that incorporates an extensive feature set. A ruggedized casing with a removable sunscreen/screen protector to enhance field use. The 4.3” TFT LCD display with 3 row hierarchical menu system provides rapid access to all features. Additional Hard keys are provided for marker movement and short cuts to major functions. On time is almost instant with the first sweep available in under 2 seconds. Addition of the U01 upgrade adds additional limit lines and patterns, data Logging, Sweep Triggers, Compensation tables, Custom Pre-sets and View on PC capability.

Ease of use was a major consideration in the design of the PSA Series 3. The menu system provides rapid access to menu groups, each of which has sub-menus, each with its own function keys. Function keys perform direct actions or create pop-up menus or dialogue boxes. Frequencies can be set by direct numeric entry, or by a digit increment system.

Centre, Start, and Stop can be stepped by any chosen increment. Span can be zoomed. Single key shortcuts include Set to Peak, Set to Marker, and Set between Markers (Start=M1, Stop=M2). Frequency presets enable fast changes between frequently used sweep ranges.

A view trace and reference trace can be displayed in addition to the live trace using contrasting colors for clarity. Any number of traces can be saved to memory and rapidly recalled to the screen. Trace states are saved in addition to the traces and can be recalled separately.

Dual markers provide an on-screen readout of frequency and level including difference values. The markers can be set to specified frequency values, scrolled across the screen, or set to automatically find peaks. A peak tracking mode is also provided which will track the highest peak in the sweep despite changing frequency. Marker amplitude readout can be in graticule units (dBm or dBµV) or in linear units (mV or µW).

Test Bridge PSA is a free application operating under Windows that provides useful file display and creation facilities. Test Bridge can display trace files that can be printed or exported to other applications. For instruments with option U01 fitted, Test Bridge provides full display and analysis of logging files, create limit pattern files, channel marker lists, and compensation tables, display live PSA screen updates.

Option U01 is a firmware upgrade that increases the capabilities of the PSA series 3 to include the following features:

Triggered sweep

The standard sweep modes of continuous repeat and single shot can be extended to include triggered sweeps from an external signal or internal limits comparison.

Limit patterns and limit comparator

Limit lines and patterns can be defined which can be simply visual aids or create automatic actions. Zone restriction can be applied. A single or dual-line limits comparator can be used to generate audible warnings, output signals, or to freeze or log the trace.

Offsets and compensation tables

The reference level, graticule, and marker readouts can be set to compensate for external attenuation or gain to a resolution of 0.1dB. Compensation can also be added for signals emanating from a 75W source. Tables can be loaded that compensate for variations of level with frequency for specific antennae or transducers. The tables can contain up to 100 points and are linearly interpolated between points.

The PSA Series 3 can log results in response to a variety of stimuli. Data is stored as files that can be transferred to a PC for analysis using PSA-Manager software. Logging entries can be created by an internal timer (adjustable from seconds up to hours), the manual trigger key, the external trigger input, or the limits comparator.

View on PC enables the screen of the spectrum analyzer to be sent to a PC by USB. The screen image can be set to a user definable size and is particularly useful for education and training purposes.
