iSlipstick RF vs VisitedPlaces

iSlipstick RF iSlipstick RF contains all of the functionality of the standard iSlipstick plus many functions specifically for RF work. RF Calculators included with iSlipstick RF are: PATH LOSS – Enter all of the RF link parameters such as transmitter output power, antenna gain, cable loss, distance and frequency to find the actual RF level at the receiver. MICROWAVE DISH BEAMWIDTH & GAIN – Enter the dish size, frequency and efficiency to find the 3 dB beamwidth and antenna gain. WAVELENGTH – Metric & U.S. RETURN LOSS / VSWR – Enter forward and reflected power to find VSWR, reflection coefficient and return loss. FRESNEL ZONE – Enter link distance, obstacle distance and frequency to find the 60% and 80% zone radii. This calculator also provides a visual display of ground clearance. VELOCITY FACTOR (VOP) – Enter the dielectric constant of a coax to find the Velocity of Propagation and enter the cable length to find the propagation delay. This calculator can also find the necessary cable length for a given delay and VOP. INTERMODULATION – Enter up to six frequencies to find the 2nd, 3rd, 5th and 7th intermod products that can be created. A 'hit' window can be set to eliminate out of band results. I.F. FREQUENCY – Enter the incoming carrier frequency and 1st local oscillator frequency to find the resulting I.F. and whether the spectrum is inverted or normal. This is a great calculator when working with up/down converters. INTERCEPT POINT – Once you have determined the levels of fundamental and intermodulation tones in a system, you can enter those values into this calculator to find either IP2 or IP3. Standard Calculators included in iSlipstick RF are: OHM'S LAW – Find voltage, current, resistance and power. REACTANCE – Find inductive and capacitive reactance by entering frequency and capacitance or inductance. RESONANCE – Find the resonant frequency of an inductor – capacitor pair. VOLTAGE DIVIDER – Enter the voltage into a resistor divider network to find the output voltage. PARALLEL RESISTOR – Enter up to six resistor values to find the resultant parallel resistance. SERIES and PARALLEL RLC – Enter R, C and L of a series or parallel circuit to find the impedance and phase angle. OP-AMP – Find the gain of either an inverting or non-inverting op-amp circuit. TIME CONSTANT - Find the first 5 time constants of both RC and RL circuits. Standard Converters included in iSlipstick RF are: RESISTOR COLOR CODE – Enter a resistor value to find the color code or enter the color code to find the resistor value. SMD RESISTOR – Enter 3 digit or 4 digit SMD codes to find the resistance value. Also does EIA-96 conversion. VOLTAGE CONVERTER – Convert between RMS, average, peak and p-p values. dB CONVERTER – Convert dBm, dBV, dBW and dBuV to absolute values and vice-versa in 50, 75 and 600 ohm load. TEMPERATURE – Convert between four popular scales. PERIOD – FREQUENCY – Convert waveform period to frequency and vice-versa. LENGTH, AREA, VOLUME, CAPACITY and WEIGHT – Convert from metric to U.S. and vice-versa. Also convert within same standard. A help page is also available as a quick function guide. Tested with iOS 12.0 thru iOS 15.1

Measure Your Working Hours with Ease Effortlessly track your working hours or time spent at specific locations—without needing to keep the app open. It runs quietly in the background, monitoring your arrival and departure even when the app is closed. The app uses your iPhone’s built-in location services to detect when you enter or leave a defined area. For best accuracy, please ensure the following settings are enabled: • Location Services • Background App Refresh • Wi-Fi It relies on Apple’s Significant Location Change and Visiting location technologies which are battery-efficient way to monitor location. You may notice the location arrow in your status bar, but unlike GPS-based tracking, this method won’t significantly affect battery life. Keeping Wi-Fi on improves accuracy. It is also the fact that in the urban areas app works better because of many cell towers and WiFi networks while in the rural areas with limited cell towers and WiFi networks it can work less accurate Getting Started is Simple: 1. Create a new place 2. Find the location on the map 3. Adjust the radius (default is 150m) using the slider
