It is alive
HEWLETT-PACKARD,83712B,US37101574,REV  10.04
Here is what to test:
startup
enable
frequency

origFreq = clk.frequency
clk.frequency = 500e6
print(clk.frequency / 1e6, 'MHz')
clk.frequency = origFreq

origEnable = clk.enable
clk.enable = not origEnable
print(clk.enable)
clk.enable = origEnable

# Context management. Downside right now is you need to go through to the config string
with clk.driver.tempConfig('FREQ', 600e6):
    print(clk.frequency / 1e6, 'MHz')
assert clk.frequency == origFreq

500.0 MHz
False
600.0 MHz
