The following scans are for a RadioShack 50 ohm dummy load. Measurements
were taken with the load directly connected to the 4170 via the BNC-SO-239
adapter included.
Device: 50Ω Dummy Load rated at 15 watts
Manuf: RadioShack (p/n: 21-506)
Feed: BNC to SO-239 adapter
scan - 1 to 181 MHz

The load exhibits a slight amount of capacitance with nearly steady Zmag
ranging from a High of 49.145Ω at 1 MHz to a low of 46.556Ω at 180 MHz. SWR
range was 1.019 to 1.363 at 180 M
