There are 6 different levels of input sensitivity between 0dBm and –50dBm in 10dB steps.
RBW=4KHz RBW=128KHz Set up the RBW (Resolution Band Width): Press the RBW key. Rotate the dial knob to select the desired RBW. Press the MHz key to validate. The RBW should be chosen as appropriate for different monitoring requirements. As the SR2000A employs modern DSP/FFT techniques, there is no difference in screen update speed regardless of which RBW has been selected. However, selection of RBW may affect displayed signal strength.
Activate the waterfall function: Press the FUNC key, then press the ATT key. Signal strength corresponds to the height of each signal in the vertical scale. Therefore, the color will vary when the input sensitivity (amplitude) has been altered in the course of monitoring. Waterfall color corresponds to the vertical height. Signal display is scrolling downwards as time progresses.
6-2 Operation Modes There are three (3) operation modes with your SR2000A. They are the Spectrum Analyzer Mode, Step Resolution Mode, and the Channel Scope Mode. To go to the Spectrum Analyzer Mode, press the FUNC key, then press the 0 key. Then press the Spectrum key on the soft keys. To go to the Step Resolution Mode, press the FUNC key, then press the 0 key. Then press the StepReso key on the soft keys. To go to the Channel Scope Mode, press the FUNC key, then press the 0 key.
z Start and End frequencies The START and End frequency can be entered in the same manner as the center frequency entry using the assigned soft keys, numeric keys and MHz key. The dial knob is not valid for the entry. [Note] The CF = MF principle In the spectrum analyzer mode and the step resolution mode, Main frequency = Center frequency When the center frequency is altered using the numeric keys or the dial knob, the main frequency is changed accordingly. The center frequency becomes the main frequency.
[Note] When the center frequency (CF) is selected and controlled with the dial knob, the monitor main frequency (MF) stays the same on display. In this case, MF is NOT equal to CF. Effective frequency coverage The center frequency (CF) must be within the frequency coverage of the SR2000A (25MHz ~3000MHz). If exceeded, monitoring is not possible. Display frequency span (MHz) is obtained by the following formula: CF +/- (display step x 160) In the above example, the center frequency is 122.50MHz.
z End frequency (Ch. END) Press the Ch. END soft key (right key below the LCD) to make the end frequency display appear in reverse contrast. Enter a desired frequency using the numeric keys, which is the highest frequency spread you wish to monitor, followed by the MHz key to confirm. z Marker and main frequency marker operation When the channel scope mode is activated, monitoring begins on the start frequency. Press the FUNC key followed by the FREQ.
z Peak detection (Peak : PEK) This feature is used to detect the most powerful signal while sweeping the frequency range. Press the PEAK soft key, which in turn requests a trigger level. You need to specify what level is required. Enter the trigger level via the numeric keys. Only signals which are stronger than the trigger level you specified will then be subject to peak detection. The marker will be forced to the position of the strongest signal detected and end its sweep sequence.
[Note] [MK.F] key functions: In the spectrum analyzer and step resolution mode, pressing the MK.F key forces the marker frequency to become the center frequency. In the channel scope mode, pressing the MK.F key will not become the center frequency. The MK.F key cannot be used in the Peak Detection mode. 6-4 Calculation function Pressing the FUNC key followed by the RBW key allows you access to three (3) calculation features: Maximum value hold (MAX), Average value (AVR) and Median (MED) value.
z Averaged value (AVR range: 2 ~ 31) Press the AVR soft key to access this feature, and the AVR icon will be displayed. You are required to enter a sampling cycle between 2 and 31 to produce averaged results. To exit from this feature, press the FUNC key, then press the RBW key, and press the AVR key. This feature is designed to provide the plot pattern obtained by averaging the signals received over the sampling cycle. A stable signal pattern is produced even if the signal is fluctuating in strength.
If the video signal frequency is below 1,000 MHz, then the AM video mode will be automatically selected. If the video signal frequency is above 1,000 MHz, then the FM video mode will be automatically selected. To activate the video function, perform the following steps: 1. 2. 3.
