+Bode Analyzer
+#############
+
+.. image:: 01_iPad_Combo_Bode.jpg
+
+This application will turn your STEMLab into an affordable Bode analyzer. It is the perfect tool for educators, 
+students, makers, hobbyists and professionals seeking affordable, highly functional test and measurement equipment. 
+The Bode analyzer is an ideal application for measuring frequency responses of the passive/active filters, complex 
+impedances and any other electronic circuit. The Gain/Phase frequency response can be used to characterize any device
+under test completely, you can perform linear and logarithmic sweeps. Gain and Phase can be measured from 1Hz to 
+60MHz. The basic user interface enables quick interaction and parameter settings. The Bode analyzer can be used for 
+the measurement of Stability of control circuits such as the DC/DC converters in power supplies, Influence of 
+termination on amplifiers or filters, Ultrasonic and piezo electric systems and similar. All Red Pitaya applications 
+are web-based and don’t require the installation of any native software. Users can access them via a browser using 
+their smartphone, tablet or a PC running any popular operating system (MAC, Linux, Windows, Android and iOS). 
+The graphical user interface of the Bode analyzer application is shown below.
+
+The graphical interface is divided into 5 areas:
+
+.. image:: BA_Slika_01.png
+
+1. **Stop/Run button:** It is used to start and stop measurement. **Calibrate button:** When the selected calibration 
+   of the setup is started.
+2. **Measurement settings panel:** It is used for setting the measurement parameters such as the frequency range, 
+   scale, number of steps, excitation signal amplitude, excitation signal DC bias and averaging number.
+
+.. image:: BA_Slika_02.png
+
+3. **Plot settings panel:** It is used to set the Gain and Phase graph ranges as also manual or auto scale mode.
+
+.. image:: BA_Slika_03.png
+
+4. **Gain graph:** The Gain frequency response of the DUT (device under test) is plotted for the selected frequency 
+   range.
+#. **Phase graph:** The Phase frequency response of the DUT (device under test) is plotted for the selected frequency 
+   range.
+
+FEATURES
+********
+
+Main feature of the Bode analyzer application are described below:
+
+    - Measured parameters: Gain, Phase
+    - The Bode analyzer application will enable you to measure the gain and phase frequency response for the desired 
+      DUT (device under test)
+    - The frequency sweep range of the Bode analyzer application is from 1Hz to 60MHz with a 1Hz resolution
+    - Linear and Logarithmic Frequency sweep modes are available. The Logarithmic sweep mode (scale) enables 
+      measurements in large frequencies range, while the linear sweep mode is used for measurement in the small 
+      frequencies range.
+    - excitation signal parameters (amplitude and DC bias) can be adjusted to make measurements in different 
+      sensitivities and conditions (amplifiers etc.).
+    - The calibration function enables calibrating long leads and to remove leads and cables effect on final 
+      measurements. The calibration will also calibrate your STEMLab if any parasitics effects are present.

 LCR meter
 *********
 
+.. image:: 01_iPad_Combo_LCR.jpg
+
+This application will turn your STEMLab into an affordable LCR meter. It is the perfect tool for educators, students, 
+makers, hobbyists and professionals seeking affordable, highly functional test and measurement equipment. The 
+Resistor, Capacitors and Inductors are basic components of all electrical circuits and working on your projects you 
+will definitely need to measure some components laying around on your working bench. The STEMLab LCR meter will enable 
+you to do that quickly and accurately just by switching from one application to another. 
+
+.. note:: 
+
+    To use the LCR meter application an additional extension module is needed. The LCR meter 
+    `extension module <http://store.redpitaya.com/red-pitaya-shield-23.html>`_ is available on our web store, 
+    `http://store.redpitaya.com/ <http://store.redpitaya.com/>`. 
+
+All Red Pitaya applications are web-based and don’t require the installation of any native software. Users can access 
+them via a browser using their smartphone, tablet or a PC running any popular operating system (MAC, Linux, Windows,
+Android and iOS). The elements on the LCR meter application are arranged logically and offer a familiar user interface
+similar to bench LCR meters.
+
+.. image:: Slika_01_LCR_meter_WEB_page.png
+
+The graphical interface is divided into 6 main areas:
+
+    1. **Hold/Run button:** It is used to start and stop measuring. Log data button: When selected, the measurements 
+       of parameters selected in the “Data options” field are logged in the table shown in area 6.
+
+    2. **Data options panel:** It is used for selecting the desired parameter for which the measurement will be
+       displayed on the Main window panel shown on area 4.
+
+    3. **Measurement option panel:** It is used to select a measuring frequency, range mode and range value. The user
+       can select between the Parallel and Series measuring modes as well as between the Tolerance, Relative or Normal 
+       modes (modes described in the features section)   
+
+    4. **Main display:** On this panel the measurements of parameter selected in “Data option” field are shown. Where 
+       the Primary parameter is shown with a larger font and the secondary parameter with smaller one. This is a very 
+       common practice since by reading values from the display the user can automatically see the most important 
+       results.   
+    5. **Secondary display:** On the secondary display the main settings are shown: current selected parameters,
+       measuring frequency and range mode. Also the Min, Max and Average value or Primary parameters are shown.   
+
+    6. **Logging table:** Is used to log and export measured data. Logging is started by selecting the “Log data” 
+       button.
+
+    7. **Option buttons field:** I used to manipulate with the table. The “Clear Min/Max” button will reset the Min 
+       and Max value on the Secondary display.

+
+FEATURES
+********
+
+The main features of the LCR meter applications are described below:
+
+MEASURED PRIMARY PARAMETERS: Z, L, C, R
+=======================================
+
+LCR meter application will enable you to measure basic parameters of the passive electrical components: 
+R – resistance, C – capacitance, L – inductance and Z – impedance.
+
+MEASURED SECONDARY PARAMETERS: P, D, Q, E
+=========================================
+
+Alongside main parameters the secondary parameters are also measured and calculated. These parameters are common in 
+describing the properties and the quality of the passive components. P – phase of the impedance (phase between current 
+and voltage on measured component), D – dissipation factor (often used to quantify the quality of the capacitor), 
+Q – quality factor (often used to quantify the quality of the inductor), ESR – equivalent series resistance
+
+SELECTABLE FREQUENCIES: 100HZ, 1KHZ, 10KHZ, 100KHZ
+==================================================
+
+LCR meter enables measurements at 4 different frequencies (100Hz, 1kHz, 10kHz, 100kHz). The user can select desired
+frequency and the LCR application will use sine signals with the selected frequency to measure the impedance.
+
+RANGE MODES: AUTO, MANUAL
+=========================
+
+Since the measured values are unknown, the LCR meter will adjust the measuring range providing the best accuracy. If 
+the user expects some value in creating ranges, then the Manual mode can be used.
+
+    - Measurements modes: Tolerance, Relative, Normal The “Tolerance” and “Relative” buttons are used for measuring in
+      the Tolerance and Relative mode. When deselected, the LCR meter measures in the Normal mode.
+    - Tolerance mode: the last value measured before clicking the Tolerance button is saved and used to calculate the 
+      percentage difference between the new value and the saved one.
+    - Relative mode: the last value measured before clicking the Relative button is saved and used to calculate
+      relative difference between the new value and the saved one. Equivalent Parameters calculation circuit:
+      Parallel, Series The Parallel and Series measuring modes refer to using the Series or Parallel equivalent 
+      circuit for the parameters (R, C, L...) calculation from the measured Impedance Z \*. LCR meters will only 
+      measure Z as the complex value Z=\|Z\|e^(jP) where P is the measured phase and \|Z\| is the impedance amplitude.
+      All other parameters are calculated from the Series or the Parallel equivalent circuit.
