Versatile measurement functions

Channel power measurement

Allows you to measure the total power or noise power in a user-specified bandwidth.

Adjacent channel power

Measure the ratio of power leakage (from the wanted signal) into adjacent channels. Center frequency, adjacent channel bandwidth, and offset between main carrier and adjacent channels can be set.

Users can select from any of the following three measurement methods based on the reference carrier definition: total power (of displayed spectrum), peak power (reference level) and in-band power (user-specified bandwidth).

Occupied bandwidth

This measurement calculates the bandwidth containing the total integrated power occupied in a given signal bandwidth. Two measurement methods are available: The user can specify N% of total power or the X dB down point relative to the carrier peak level.

Calculation and marker functions

Maximum and minimum hold

Maximum hold: At each displayed frequency, the currently-measured value is compared to the previously-measured value and the larger one is retained and displayed. This feature is useful for observing a bursted or intermittent signal or for measuring the electric field strength of systems using direct sequence spread spectrum/frequency hopping modulation techniques.

Minimum hold: At each displayed frequency, the currently-measured value is compared to the previously-measured value and the smaller one is retained and displayed.

In both cases, the number of sweeps can be set to 2^N, where N is from 1 to 10 or infinite.

Averaging

The analyzer continuously sweeps, then calculates and displays the average value over the total number of sweeps. The number of sweeps can be set to 2^N, where N is from 1 to 10. Averaging is useful for detecting signals buried in the noise floor because random noise is averaged out.

Overwrite

The results of each consecutive sweep are displayed and the screen is not cleared after each sweep. This lets you observe the long term variations of a signal.

Marker function

Two different modes are available for marker measurements:

• Normal marker mode measures the frequency and level of the marked point
• Delta marker mode measures the frequency and level differences between the two markers

Peak function

Two different modes are available for peak search:

• Normal peak search mode searches for the highest level on the screen. In this mode, you can also use the NEXT button to locate the marker on the next smaller peak
• In-zone peak search mode searches for the peak level in the range specified by the center value and width

Easy operation

This handheld spectrum analyzer is straightforward to operate and provide many functions to facilitate quick and easy measurements:

• Smart one button “Auto Tune" function which automatically scans the full frequency range, detects and centers the maximum signal, and configures optimum values for RBW, VBW, sweep time and reference level
• Input attenuator and internal preamp are set automatically to optimal values based on the reference level
• Easy configuration of frequency, span, and amplitude
• Marker and peak search functions enabling rapid measurements
• 200 setups and reference spectrum measurements can be stored and recalled from either internal memory or USB flash drive
• Filenames can be customized and include a date and time stamp
• Large easy-to-read display. The backlight is adjustable and monochrome mode can be used for extreme lighting conditions

Long battery life

Provides a battery operating time of up to 4 hours (approximately 3½ hours with back light set to typical settings). Battery replacement is simple and doesn't require any hand tools. To fully charge the lithium-ion battery takes only approximately 4 hours (analyzer must be turned off). A two color LED indicates the charging status "charging", "charge completed", "no battery detected" and "charging error".

Simple and flexible documentation of your measurements

PC software

Includes easy-to-use software for documentation and further analysis of your measurements. Connect the analyzer via USB cable to your PC, configure the analyzer remotely, then download measurement data and instrument settings for storage and further analysis.

• Continuously sweep and transfer trace data to the PC
• Capture 1001 trace data points (twice the number of display dots) and store the data in CSV (comma separated values) format for detailed analysis (e.g., import into a spread sheet)
• Save the screen to a bitmap file or to the clipboard
• Control all instrument settings from the PC
• Download custom antenna gain factor compensation data to the instrument

Conveniently save measurement data to USB flash drive

Easily save and recall measurement data and settings in CSV format directly to and from the USB flash drive. Filenames can be customized and have a time and date stamp. Users can choose to store measurement data and setups in separate files or combined in one file.

Using the Copy function, a screen image in bitmap format (BMP) can be directly stored to the USB drive. CSV data residing in internal memory can be stored to the USB drive in a lump sum.
