1L40_front.jpg | 1L40_front.jpg|Front view | ||
1L40_threequarter.jpg | 1L40_threequarter.jpg|Threequarter view | ||
1L40_right.jpg | 1L40_right.jpg|Right side view. Note the housing for the removable input mixer at bottom left, and the tuned cavity for the 1st local oscillator at the top. | ||
1L40_left.jpg | 1L40_left.jpg|Left side view. | ||
1L40_rear.jpg | 1L40_rear.jpg|Rear view. Note the selector switch to adapt the sweep input voltage to different models in the 500 series range. | ||
1L40_bottom.jpg | 1L40_bottom.jpg|Bottom view. | ||
1L40_top.jpg | 1L40_top.jpg|Top view. Cavity for the 1st local oscillator is on the right, and the tuning mechanism is visible. IF filters and attenuators are in the can in the middle. | ||
1L40_input_closeup.jpg | 1L40_input_closeup.jpg|Input connector. This is the basic 1.5-12.4GHz input, which can be removed and replaced with an extension cable to waveguide mixers for higher frequencies. | ||
1L40_dial_closeup.jpg | 1L40_dial_closeup.jpg|Closeup of RF centre frequency dial. Fundamental range is at the bottom with harmonics above. | ||
1L40_dispersion_switch_closeup.jpg | 1L40_dispersion_switch_closeup.jpg|Closeup of part of the dispersion range switch assembly. Note the two little fingers attached to the shaft which operate the toggle switch. | ||
1L40_in_535A_2100MHz.jpg | 1L40_in_535A_2100MHz.jpg|1L40 in 535A mainframe tuned to 2100MHz cellular band showing signals. 5MHz/div dispersion. | ||
1L40_2100MHz_closeup.jpg | 1L40_2100MHz_closeup.jpg|Tuned to 2100MHz cellular band (5MHz/div dispersion) showing 3G data downlinks from various operators. From the right: Orange, T-Mobile, Plus and Play. Photo taken in Warsaw, Poland, January 2018. | ||
1L40_IF.jpg | 1L40_IF.jpg|Signals displayed straight through the plugin's 150-250MHz IF. Dispersion 5MHz/div, centre frequency 200MHz. The peak on the left is the local DAB radio multiplex on channel 6B, 183.648MHz. The hump to the right of that looks like a DVB-T multiplex on channel 7, but I can't identify it. Photo taken in Warsaw, Poland, January 2018. | ||
