Impairment Measuring Set (TIMS). The transmission impairment

The HP 4934A can make measurements directly on leased lines
or on dial-up lines. It has loop holding capability, a
monitor speaker and butt-in connection (useful for talking
to the far end of the test line).
There are four permanently stored frequencies 404 Hz, 1004
Hz, 2804 Hz and 2713 Hz. Any other four frequencies may be
temporarily assigned and stored by the user.
The HP 4934A can test circuits using single frequency (SF)
signaling - use the SF SKIP feature. SF SKIP prevents the HP
4934A from transmitting signaling frequencies in the range
2600 Hz ±150 Hz.
