Description
BK Precision DDS Sweep Function Generator 20 MHz - Model 4040BModels 4014B and 4040B are versatile sweep function generators, designed with a dual technology architecture combining direct digital synthesis (DDS) and a low jitter square wave generator. These instruments generate sine, square, and triangle waveforms with high signal precision and stability. Both models provide variable output voltages from 0 to 10 Vpp into 50 ohms (up to 20 Vpp into open circuit), linear and logarithmic sweep, AM FM modulation,
Models 4014B and 4040B are versatile sweep function generators, designed with a dual technology architecture combining direct digital synthesis (DDS) and a low-jitter square wave generator. These instruments generate sine, square, and triangle waveforms with high signal precision and stability. Both models provide variable output voltages from 0 to 10 Vpp into 50 ohms (up to 20 Vpp into open circuit), linear and logarithmic sweep, AM/FM modulation, and a continuously variable DC offset to inject signals directly into circuits at the correct bias level.- Sine, square, and triangle/ramp waveform generation
- Bright color LCD display with waveform preview
- Linear and logarithmic sweep
- AM/FM modulation
- Adjustable duty cycle
- Independent DC offset amplifier design allows large offsets on small amplitude (e.g. 10 mV) waveforms
- Store and recall instrument settings
- Output On/Off button
- Internal/external triggering
- Gate and burst mode (4040B only)
- Built-in counter
- USB interface with SCPI-compliant command set
- Short circuit and overvoltage protection on all inputs and outputs

REALLY unsafe to walk around in these
Size: 2 pairs black L
They do what they are expected to do, but should only be used if you are stationary. The gel base makes for very unstable footing if walking around

These work
Size: 2 pairs black L
My husband loves these they help his very dry feet. As others have stated they are extremely difficult to walk in so have to be careful but they do work nicely.

Potential Fall Risk
Size: 2 pairs black L
While these socks do indeed help soften rough skin on your feet, there is a risk of falling while wearing them. Although they have treads on the bottom, which would indicate they’re safe to wear with nothing else, when you put moisturizer on and then wear them your foot can slip inside the sock . This causes you to lose your balance and fall, which happened to me. I’ve thrown them out.

I could be a foot model now!!!
Size: 1 pair black L
I wear work boots almost all of the time so I bought these to put on my feet with salycylic acid to moisturize and try to get rid of a stubborn corn on the ball of my foot. It helped drastically after a few nights of lounging in the house with them on.
