Introduction
The LP-100A is designed as an accurate instrument for monitoring station performance. It provides a number of unique features not
seen before in a ham radio wattmeter.
The most obvious of these is the vector display. This display shows the complex impedance of the load in two ways. The top line of the
display shows impedance in polar form… i.e., magnitude and phase of the impedance. The bottom line shows the real and imaginary
components of impedance… i.e., R +jX. The parameters are displayed in a range of 0.1 to 999.9 ohms. Phase is displayed in 0.1
degree increments from 0-90 degrees.
Features include…

Fast, high contrast GVFD display with bargraphs for power and SWR, along with numerical readout for both

Bargraphs customizable for style, decay, behavior and range

Professional dBm / Return Loss display

50 mW to 3000W with three autoranging scales (options for 5 & 10KW)

Power display resolution of 0.01 to 1W depending on scale

Frequency coverage of 1.8-54 MHz, with automatic per-band correction

Z, R, |X| display from 0-999.9 ohms each

Separate coupler with 50 ohm ports for uncluttered desktop

Peak-hold numerical power readout with "hang" characteristic for power and SWR

SWR accuracy < .15 (5%) from about .1W to 3000W, .05 typical

Power accuracy is 3% typical at any rated power level or frequency from 1W to 3000W after calibration, usable to 0.05W

Can be easily matched in the field to external standard to within 0.1% on each band

Power display is Fwd or Net power delivered to the load ( Fwd minus Ref power).

SWR Alarm system with set points for Off, 1.5, 2.0. 2.5, 3.0 and user setting. Includes “snooze” button for tuning, and power threshold.

Windows freeware Virtual Control Panel for software / remote control

Support within TRX-Manager for direct remote monitoring

Advanced automatic charting capability for SWR, RL, Z, R, X , reflection coefficient and Smith Chart

Built-in bootloader to allow for firmware upgrades to be downloaded and installed.

Call sign screen saver to extend life of display, scrolls a full screen call sign across the screen. Call sign is set in Setup screen.

Direct input for bench testing & field strength measurements, -15 to +33 dBm.

Conforms to FCC Part 15 A & B, ICAS and CE radiated emission limits, tested and verified by accredited lab
This manual will address the operation of the LP-100A. For those who are interested, there is also a section on Calibration, even
though this is already done at the factory. There is an Appendix with interesting information the user might find useful.
RoHS Statement
The EU adopted a set of standards for the “Reduction of Hazardous Substances” in July 2006. LP-100A’s shipped to EU are 100%
RoHS compliant in both parts and manufacturing processes. There may be some long term reliability issues associated with RoHS
compliant solders and parts, but unlike some industries like aerospace and medical, we are not exempt from these rules. We have seen
no indication of reduced performance or longevity.
